At the end of the story of the great flood God places a rainbow in the sky as a token of the covenant between God and all the people of the earth.
Why does God choose the rainbow? The rabbis teach us that the rainbow is an appropriate symbol of peace because it is made up of many different colors, and when you look at it, it is impossible to distinguish one color from the next.
The rainbow reminds us that even though no two humans are alike, we are all part of one covenant with God. Like the colors of the rainbow, we are all different, and yet we are all God’s children and we all have a share in the fulfillment of that covenant to help God create a world of Shalom.
God decides to cause a flood that will destroy the world, sparing only Noah’s family and the animals that Noah gathers together on the ark. (6:9-8:22)
Life starts over again after the Flood. The Noahide Commandments are listed, and God uses a rainbow to make a symbol of the first covenant. (9:1-17)
People start to build a city and the Tower of Babel. God scatters the people and gives them different languages to speak. (11:1-9)
The ten generations from Noah to Abram are listed. (11:10-29:2)
