Joe: Alright, so we have Bible Expert here to talk about the book of Genesis. What's in Chapter 21?

Bible Expert: Well Joe, Chapter 21 is a continuation of the story of Abraham and Sarah. They've been promised a son by God, and in this chapter they finally get their wish. They name him Isaac.

Joe: Wow, what a miracle! So, what else is in this chapter?

Bible Expert: Well, Sarah is so happy with the birth of her son that she offers her maidservant, Hagar, and her son Ishmael to Abraham. Abraham then sends Hagar and Ishmael away, and God blesses them.

Joe: Whoa, that's a lot of drama. What else?

Bible Expert: Well, this chapter also contains the Covenant of the Pieces. God promises Abraham that his descendants will be as numerous as the stars in the sky.

Joe: Wow, that's a huge promise. Anything else?

Bible Expert: Yes, there is one more thing. God also makes a covenant with Abraham that his descendants will possess the land of Canaan.

Joe: Wow, that's a huge promise! Alright, well, we have to take a break, but when we come back we'll talk about Chapter 22.
