Genesis 21:25-30

25One day, Abraham complained to Abimelech about a certain well of water. Abimelech's servants had taken the well from Abraham. They said that the well belonged to them.

26Abimelech said, ‘I do not know who has done this. You did not tell me before. I did not hear about it until today.’

27So Abraham brought some sheep and some cows and he gave them to Abimelech. The two men made a promise to help each other.

28Abraham took seven female lambs from the sheep. He put them in a different place from the other animals.

29Abimelech asked Abraham, ‘Why have you put these seven lambs in a different place?’

30Abraham replied, ‘You must accept these seven lambs as a gift from me. That will show that you agree that I dug this well. Everyone will know that it belongs to me.’
