Read Plato's Laws:
1. Ideal society is 12 tribes
2. Set a foundation story of conquest or colonization
3. Gives laws as if they come from a divine being (Plato was a monotheist)
The creation story in Genesis 2 is paralleled in Symposium and Timaeus.
As for Iliad David's story is paralleled closely. Note the story in 1 Samuel 17 with Goliath.
The stories of Noah's drunkenness' and the three angels visiting abraham are taken right out of Baucis and Philemon.
As for Jephthah and his daughter and the closely related Abraham and Isaac binding story. These are taken from Agamemnon and Iphigeneia
