Genesis chapter 21

After reading chapter 21:

* Now, the promised child is born to Abraham and Sarah when they are about 100 and 91 years old. Wonder of wonders, miracle of miracles! He is named Isacc and circumcised at eight days.

*Isaac grew, and on the day of the celebration of Isaac's weaning, teenager Ishmael was being rude. Sarah told Abraham to get rid of Ishmael and his mother. There was no way her son would share an inheritance with him.

*Abraham actually showed some feeling for Ishmael. God, however, tells him to do what Sarah says. It's okay because both Isaac's and Ishmael's descendents will become great nations. So it doesn't matter how Ishmael and his mother feel about it. Off they were sent into the desert with only some water. Every thing worked out though, because an angel called out from heaven and told them God heard them crying.

*Abraham and Abimelech make a treaty of mutual cooperation and Abimelech acknowledges Abraham's ownership of the well at Beersheba, which will appear again later. Abraham plants a tree there and calls upon the name of the name of the lord (Yahweh) the eternal God (El). He stayed in that land of the Philistines a long time.

*This is the first mention of Philistines. There is no clear historical record of who the Philistines were, but there is lots of speculation.
