Gen 9:9-17. God announces His first covenant with man, that He will never again destroy the earth with a flood. He doesn't rule out other catastrophes. (God, apparently, is the opposite of an insurance company. He offers flood protection, but no other coverage.)
[Gen 18]: Jews had the three wise men before Jesus! Three strangers visit Abraham, and he welcomes them hospitably. One of the strangers—who are messengers of God—announces, "I will return to you next year, and your wife Sarah shall have a son." The Christ story is a clear rip-off. In the Christmas tale, it's impossible for Mary to have a child because she's a virgin, but she does, and three supernatural visitors herald the child's birth. Here it's impossible for Sarah to have a child because she's post-menopausal (as we are told very directly: "Sarah had stopped having the periods of women")—but she does, and three supernatural visitors herald it. The big difference: We Jews do not have any good songs about this incident.
[Gen. 23] Real estate, again! It is the strangely dominant theme of Abraham's life. Practically every chapter about him is crammed with details about land—who owns it, who can buy it, whether God is giving it, whether it's a temporary deal or a permanent one. There's more about real estate than there is about the Lord.
