Genesis 9:23-25 NLT, reads,
Then Shem and Japheth took a robe, held it over their shoulders, and backed into the tent to cover their father. As they did this, they looked the other way so they would not see him naked. When Noah woke up from his stupor, he learned what Ham, his youngest son, had done. Then he cursed Canaan, the son of Ham: “May Canaan be cursed! May he be the lowest of servants to his relatives.”
He couldn't be that bashful. What's going on here?
