God changes Abram's name to Abraham
1 When Abram was 99 years old, the Lord appeared to him. The Lord said, ‘I am God Almighty. In all your life, obey me and do nothing wrong. 2 Then I will certainly keep my covenant with you. I will make your descendants grow in number.’
17:2God had already promised Abram that he would have very many descendants. See Genesis 15:4-5. Here, God was helping Abram to remember his promise. Abram should continue to trust God.
3 Abram fell down so that his face touched the ground. God said to him, 4 ‘As for me, this is my covenant that I have made with you. You will become the ancestor of many nations of people. 5 Your name will not be Abram any more. Instead your name will be Abraham, because I will cause you to become the ancestor of many nations. 6 I will give you many descendants. These will make many nations of people. Some of your descendants will become kings.
7 My covenant with you is very strong. I am making it with you and with your descendants. It will continue for generation after generation of your descendants, for all time. I will be your God. I will also be the God of all your descendants. 8 You are now living here in Canaan as a foreign person. But I will give all of this land to you and to your descendants. It will belong to them for ever. I will be their God.’
