Noah and his family are in G-d’s favor while he views the rest of the world as corrupt. G-d instructs Noah to build an arch, coated with pitch inside and out, to keep his family safe in addition to 2 of every species (and 7 each of the pure species).
It rains for 40 days and 40 nights. The flood annihilates all that exists on the land and recedes after 150 days. One year after the flood, Noah is instructed to repopulate the Earth.
After Noah builds an alter and burns a sacrifice for G-d, the aroma is so pleasing and wonderful that G-d vows never to destroy mankind again. Rainbows will be a reminder of that covenant. Murder is deemed a capital offense and it is told that you cannot eat meat with a soul – you can only eat the meat from an animal that is dead.
Noah’s son Ham is condemned for taking advantage of Noah while he had over imbibed on wine while his sons Shem and Japheth are blessed for covering his nakedness.
Noah and his descendants populate the earth for 10 generations. They all have one language, one culture, and feel emboldened to build a tower to their greatness. G-d then confuses their speech and Noah’s descendants scatter to form 70 nations who cannot understand each other anymore.
The parashat ends following Noah’s descendants for 10 more generations until Abraham is born and begins his journey to Canaan.
