Listen up, rookies! Gen-17: Ya'll better get it together! God tells Abram He's gonna make him into a great nation. He'll get a new name: 'Abraham', and he'll be a father of many nations. Sarai, his wife, gets a new name too: Sarah. God gives them a commandment: Circumcise every male in their family. That's right, every male - no exceptions! Oh, and He also gives Abraham and Sarah a sign: the covenant of circumcision. Finally, God promises to give Abraham and Sarah a son. His name will be Isaac. So don't forget it - Gen-17: Circumcise every male, get a new name, and accept God's covenant! Dismissed!
