1. Noah became drunk (18-21)

Noah was blessed by God to start a new history with the rainbow covenant. He planted a vineyard. He became accidentally drunk from the wine. He lay uncovered inside his tent. When God blesses, we need to be more careful. When God blessed David with many victories, his heart was complacent and was tempted to commit adultery. But Jesus never gave Satan any chance to tempt him by going to pray always after big successes and events (John 8:1). In the same way, we must pray continually (1 The 5:17), for our enemy Satan is like a prowling lion to devour anyone. (1 Pet 5:8)

2 Noah's curse (22-29).

The behavior of Ham, the father of Canaan, is sharply contrasted with that of Shem and Japheth toward their father's fault and mistake. Ham saw Noah's nakedness and reported it to his brothers. But Shem and Japheth walked backward not to see Noah's mistake and covered his naked body with a garment. Noah's curse to Ham's descendants shows us two things; the historical legitimacy of conquering Canaan by Israel; and we must cover the faults and mistakes of our leaders or fathers rather than point them out with contempt.
