Genesis 9:23

And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father's nakedness.

1. Shem and Japheth cleverly covered their father, Noah, without seeing him naked.
2. Shem and Japheth were either afraid or just didn't want to see their father naked.
3. In either case I wonder why it wasn't Ham and one of the others who did this. After all, Ham had already seen Noah. Why not minimize the risk of another seeing him?
4. Why didn't the brothers just wait for Noah to awaken and cover himself?
5. One's uncovered body is apparently not something for others to see, with the exception of one's spouse, as taught in the Adam and Eve story.
