20 Then Noah built an altar to the Lord and took some of every clean animal and some of every clean bird and offered burnt offerings on the altar. 21 And when the Lord smelled the pleasing aroma, the Lord said in his heart, “I will never again curse the ground because of man, for the intention of man's heart is evil from his youth. Neither will I ever again strike down every living creature as I have done.’ 22 While the earth remains, seedtime and harvest, cold and heat, summer and winter, day and night, shall not cease.”
1 And God blessed Noah and his sons and said to them, “Be fruitful and multiply and fill the earth. 2 The fear of you and the dread of you shall be upon every beast of the earth and upon every bird of the heavens, upon everything that creeps on the ground and all the fish of the sea. Into your hand they are delivered. 3 Every moving thing that lives shall be food for you. And as I gave you the green plants, I give you everything. 4 But you shall not eat flesh with its life, that is, its blood. 5 And for your lifeblood I will require a reckoning: from every beast I will require it and from man. From his fellow man I will require a reckoning for the life of man.
6 “Whoever sheds the blood of man,
by man shall his blood be shed,
for God made man in his own image.
7 And you, be fruitful and multiply, increase greatly on the earth and multiply in it.” – Genesis 8:20-9:7 ESV
Upon exiting the ark, Noah immediately demonstrates his immense gratitude for God’s salvation of him and his family. He erects an altar and offers sacrifices to God. But this response stands out as rather odd considering the context of chapter eight. Noah has just been spared from death. And he had been used by God to protect the lives of “animals and creeping things and birds of the heavens” (Genesis 6:7 ESV). God had given him the responsibility of gathering pairs of animals and placing them on the ark so that they might survive the flood.
“And of every living thing of all flesh, you shall bring two of every sort into the ark to keep them alive with you. They shall be male and female. Of the birds according to their kinds, and of the animals according to their kinds, of every creeping thing of the ground, according to its kind, two of every sort shall come in to you to keep them alive.” – Genesis 6:19-20 ESV
And yet, chapter eight closes with Noah taking the lives of some of the animals he just helped save. This all seems so counterproductive. And where did Noah get the idea of constructing an altar and offering burnt offerings to God? This is the first mention of the term “altar” in the entire Bible, and it comes long before God gave to Moses His commands concerning the sacrificial system. It seems doubtful that this costly act of animal sacrifice was something Noah came up with on his own. God had obviously made preparations for just such an occasion because He had commanded Noah to “Take with you seven pairs of all clean animals, the male and his mate, and a pair of the animals that are not clean, the male and his mate, and seven pairs of the birds of the heavens also, male and female, to keep their offspring alive on the face of all the earth” (Genesis 7:2-3 ESV).
In Hebrew, the term translated as “clean” is טָהוֹר (ṭâôr), and it means “pure.” It was used to refer to that which was pure or clean physically, but also those things that were considered ceremonially and morally pure. God had specifically provided Noah with two different lists of animals to collect and protect on the ark. Of the “clean” animals, Noah was to gather seven pairs. But of those animals deemed “unclean” by God, Noah was to gather only one pair of each – a male and a female.
God was obviously making plans for the future. And He must have given Noah strict instructions as to how to differentiate between the clean and unclean animals. It is likely that God provided Noah with a similar list as that found in Leviticus 11.
“Of all the land animals, these are the ones you may use for food. You may eat any animal that has completely split hooves and chews the cud. You may not, however, eat the following animals that have split hooves or that chew the cud, but not both. The camel chews the cud but does not have split hooves, so it is ceremonially unclean for you. The hyrax chews the cud but does not have split hooves, so it is unclean. The hare chews the cud but does not have split hooves, so it is unclean. The pig has evenly split hooves but does not chew the cud, so it is unclean. You may not eat the meat of these animals or even touch their carcasses. They are ceremonially unclean for you.” – Leviticus 11:2-8 NLT
God went on to give Moses a detailed list of all the sea creatures, birds, and winged insects that were to be considered clean and good for food. And it seems only logical that God provided Noah with a similar list. Otherwise, he would not have known which species required seven pairs rather than two. Since God had deemed these living creatures as clean and approved for eating, He was ensuring that humanity would have an ample post-flood food source. When Noah exited the ark, God gave him express permission to consume animals as well as plants.
“Every moving thing that lives shall be food for you. And as I gave you the green plants, I give you everything.” – Genesis 9:3 ESV
While this verse placed no restriction on the eating of unclean animals, it is inferred by the surrounding context. The whole purpose behind God differentiating between the clean and unclean creatures was so that Noah and his family knew which animals were approved as sources of food. But God had a second reason for setting apart the clean animals and instructing Noah to collect more of their kind. He had obviously given Noah instructions regarding the offering these pre-approved creatures as animal sacrifices. All the way back in Genesis four, the two sons of Adam inherently knew that they were to bring offerings to God.
In the course of time Cain brought to the Lord an offering of the fruit of the ground, and Abel also brought of the firstborn of his flock and of their fat portions. – Genesis 4:3-4 ESV
Now, centuries later, and after God had spared Noah and his family. the offerings were to continue. This time, God must have instructed Noah to build an altar and offer up a portion of the clean animals as an offering of thanksgiving. But there is something more to this act of sacrifice. In giving up these particular animals, Noah was willingly diminishing his food source. He was letting go of the very thing that was supposed to ensure the future well-being of him and his family. And, in doing so, he was displaying his trust in God. Those animals sacrificed would never breed again. They would never serve as a source of food or clothing. Noah effectively gave them back to God. And God was pleased.
“…when the Lord smelled the pleasing aroma, the Lord said in his heart, ‘I will never again curse the ground because of man, for the intention of man's heart is evil from his youth.’” – Genesis 8:21 ESV
God made a categorical decision to never destroy the earth again, in spite of the fact that nothing had really changed. God reveals that, despite Noah’s obedient sacrifice, the heart of man remained as wicked and fallen as ever. God was starting over with Noah and his family, but He knew that they were damaged goods. In a way, the sacrifice of the “pure” animals was a foreshadowing of the sacrificial system God would ordain for the people of Israel. Because of their sinful dispositions, He would provide them with an ongoing means of atonement for sin, in the form of animal sacrifice. In time, those pure and undefiled animals would be necessary, not just for food, but for cleansing from sin. Why? Because despite the purging and purifying effects of the flood, the heart of man remained permanently marred by evil.
But God made a covenant commitment to Noah, promising to never repeat the devastating destruction of the flood. Instead, He would give humanity a second chance. God chose to give Noah and his family an opportunity to fulfill the same kingdom mandate given to Adam and Eve.
“Be fruitful and multiply and fill the earth.” – Genesis 9:1 ESV
Everything was starting over. The old world had been destroyed. God was beginning again with a new vice-regent: Noah. This “second Adam” was given dominion over all the creatures of the earth. He was awarded stewardship of God’s creation, but this time, God provided Noah with some new stipulations concerning his role.
“Every moving thing that lives shall be food for you. And as I gave you the green plants, I give you everything. But you shall not eat flesh with its life, that is, its blood. And for your lifeblood I will require a reckoning: from every beast I will require it and from man. From his fellow man I will require a reckoning for the life of man.” – Genesis 9:3-5 ESV
Unlike Adam and Eve, Noah and his family were given divine permission to use the animals as an alternate food source. But this alteration to their daily diet came with restrictions. They were not allowed to consume the blood of the animal. Much later, God would give the people of Israel further instructions and clarification regarding this ban on the consumption of blood.
“For the life of every creature is its blood: its blood is its life. Therefore I have said to the people of Israel, You shall not eat the blood of any creature, for the life of every creature is its blood. Whoever eats it shall be cut off.” – Leviticus 17:14 ESV
According to the creation account, every beast of the earth, every bird of the heavens, and everything that creeps on the earth contained the breath of life (Genesis 1:30). And when God had breathed the breath of life into Adam, he had become a living creature (Genesis 2:7). But the life of every creature is contained in its blood. This incredible substance, created by God, is what sustains the life of every living creature.
The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body.
Blood carries the following to the body tissues:
Nourishment
Electrolytes
Hormones
Vitamins
Antibodies
Heat
Oxygen
Immune cells (cells that fight infection)
Blood carries the following away from the body tissues:
Waste matter
Carbon dioxide

Life cannot exist without blood. And so, God put a prohibition on the consumption of blood. In the animal kingdom, this restriction is regularly ignored, and they suffer the consequences. Wild animals are destined to live in a perpetual cycle marked by carnivorous consumption. But for man, it was to be different. He was not to kill an animal and eat its blood. If he did, he would suffer the consequences. And if a man spilled the blood of a fellow human being, he would pay dearly.
“If anyone takes a human life, that person’s life will also be taken by human hands. For God made human beings in his own image.” – Genesis 9:6 NLT
Things were going to be different in the post-flood world. In the antediluvian world, Cain had killed Abel and had lived to tell about it. Lamech had murdered a man and had bragged about it. But now, God would deliver stern judgment upon all those who took it upon themselves to play god and take human life.
And, having laid out the new rules of engagement in His recreated world, God reiterated His original mandate to humanity.
“…be fruitful and multiply, increase greatly on the earth and multiply in it.” – Genesis 9:7 ESV
