The Abrahamic covenant is confirmed in part and expanded to include a provision that is conditional. God adds a mutual provision, with conditions for Abraham to meet in order to receive added blessings. Abram and Sarai’s names are changed by God. The sign of the covenant, circumcision, is established and the promise of Isaac and his descendants is given. The events of chapter 17 take place 13 years after chapter 16.



Genesis 17:1-2

When Abram was 99 years old, God established a covenant with him to bless him greatly if he walked blameless. God expanded His covenant to add this mutual condition, where Abram would receive blessings if he walked in righteousness.

Genesis 17:3-5

God changes Abram’s name to Abraham because he will be the father of many nations.

Genesis 17:6-8

God promises that many nations and kings will come from Abraham’s descendants. God’s covenant is never-ending, and He promises to give the land of Canaan as a perpetual possession to Abraham’s descendants. God also indicates that His covenant extends to Abraham’s descendants after him. This would include the benefit of the rewards already granted as well as the conditional promise to bless them when they live faithfully.

Genesis 17:9-11

God commands Abraham that every male who keeps the covenant must be circumcised as a sign of the covenant.

Genesis 17:12-14

God gives further instructions about circumcision; Male babies who are 8 days old, even servants either born or bought must be circumcised. Anyone who is not circumcised has broken God’s covenant.

Genesis 17:15-17

God changes Sarai’s name to Sarah and promises she will birth a son. Abraham laughed that a man 100 and his wife 90 years old could have a child.

Genesis 17:18-20

Abraham presumes God meant that His promises to bless him and his descendants would come through Ishmael. But God says His covenant will be established through a son born to Sarah. His name will be Isaac.

Genesis 17:21-23

When God had finished talking, Abraham immediately took all the males in his household and circumcised them as God had commanded.
