Genesis 9 covers three things.
First, it elaborates on God's covenant between Himself and all living--that He will not destroy all life with a flood again. He sets a rainbow in the sky as a symbol of promise to all generations.
Second, the chapter records God giving dominion over all living creatures to man. I will be noting this passage under "Significance of Man."
Thirdly, world history after the flood is begun with an account of Noah in an awkward situation and how his children respond. I will start a new post to deal with alcohol and drunkenness and make note of this early passage.
