Genesis 15:12-18

12When the sun was going down, Abram started to sleep. Suddenly he became very afraid because it was dark all around him.

13Then the Lord said to Abram, ‘Be sure of this: Your descendants will live in a foreign country. They will be strangers there. People will do bad things to them and they will become slaves. This will continue for 400 years.

14But I will punish the people of that country who give them trouble. After this, your descendants will leave that country. They will take many valuable things with them.

15But as for you, Abram, you will have a long life. When you die, you will have peace in your mind.

16After four generations, your descendants will come back here to Canaan. At that time, I will punish the Amorites because they do very bad things. But the time has not yet arrived that I will punish them.’

17Then the sun went down and it became dark. Abram saw a pot that had coals in it. The coals were burning and making smoke. There was also a branch that burned with bright fire. These passed between the halves of the animals that Abram had cut in two pieces.

18On that day, the Lord made a covenant with Abram. The Lord promised, ‘I give this land to your descendants. The land starts from the river of Egypt and continues as far as the River Euphrates.
