The very FIRST covenant, my covenant, of Genesis 9
OK, lets explore that....
Genesis 9:1-17:
"God went on to bless Noah and his sons and to say to them: “Be fruitful and become many and fill the earth."
This is a restatement of God's mandate to Adam and his wife after their creation (Genesis 1:18)....but the one notable omission was "to subdue" the earth. When humans lost their perfection, the second part of the mandate had to wait until God had addressed the problem of man's disobedience and loss of direct access to their Creator.
"2 A fear of you and a terror of you will continue upon every living creature of the earth and upon every flying creature of the heavens, upon everything that moves on the ground and upon all the fish of the sea. They are now given into your hand."
A fear of man was now instilled into the animals, which was obviously missing prior to the flood. Being given into the hand of man, they were now vulnerable and given the ability to exercise caution with humankind and each other.
"3 Every moving animal that is alive may serve as food for you. Just as I gave you the green vegetation, I give them all to you. 4 Only flesh with its life—its blood—you must not eat."
Man was given permission to eat flesh for the first time, meaning that prior to the flood, all humans and probably all animals were vegetarians. This is the first of three prohibitions on the consumption of blood given in the scriptures. Animals were to be properly bled before being eaten. Respect for the creature's lifeblood was acknowledged by pouring it out on the earth.
In the new earth to come, prophesied by Isaiah, carnivorous animals were to go back to eating "straw like the bull". (Isaiah 11:6-9)
"5 Besides that, I will demand an accounting for your lifeblood. I will demand an accounting from every living creature; and from each man I will demand an accounting for the life of his brother. 6 Anyone shedding man’s blood, by man will his own blood be shed, for in God’s image He made man."
This was a warning about shedding human blood. God would demand an accounting.
"7 As for you, be fruitful and become many, and increase abundantly on the earth and multiply.”
Replenishing the earth now rested upon one family again, and their descendants would become many and fill the earth as God directed. All humans living now owe their lives to Noah.
"8 Then God said to Noah and to his sons with him: 9 “I am now establishing my covenant with you and with your offspring after you, 10 and with every living creature that is with you, the birds, the animals, and all the living creatures of the earth with you, all those that came out of the ark—every living creature of the earth. 11 Yes, I establish my covenant with you: Never again will all flesh be destroyed by the waters of a flood, and never again will a flood bring the earth to ruin.”
So a promise was made by God never to flood the world again....but it is obvious that humans have invented ways to do that themselves. Global warming may very well be responsible for many low lying land areas being inundated.
"12 And God added: “This is the sign of the covenant that I am making between me and you and every living creature that is with you, for all future generations. 13 I put my rainbow in the cloud, and it will serve as a sign of the covenant between me and the earth. 14 Whenever I bring a cloud over the earth, then the rainbow will certainly appear in the cloud. 15 And I will certainly remember my covenant that I made between me and you and every living creature of every kind; and never again will the waters become a flood to destroy all flesh. 16 And the rainbow will occur in the cloud, and I will certainly see it and remember the everlasting covenant between God and every living creature of every kind on the earth.”
17 God repeated to Noah: “This is the sign of the covenant that I establish between me and all flesh that is on the earth".
Often called the "Rainbow Covenant" this was God's promise never to ruin the earth again by a flood. He regretted that man had become so wicked, so quickly due to the influence of rebellious angels producing a super race of gigantic bullies who had no right to live, so God's response was to eliminate them from existence and start again. It was only a stop-gap measure however, to bring his purpose back on track. Mankind were still suffering the effects of sin, which would only be removed by the atoning blood of a specific sacrifice to come.
This is only one of many covenants that God made with his worshippers. He has never ever broken a covenant.
