Genesis 21:24-30
English Standard Version
Chapter 21
24And Abraham said, "I will swear."
25When Abraham reproved Abimelech about a well of water that Abimelech 's servants had seized,
26Abimelech said, "I do not know who has done this thing; you did not tell me, and I have not heard of it until today."
27So Abraham took sheep and oxen and gave them to Abimelech, and the two men made a covenant.
28Abraham set seven ewe lambs of the flock apart.
29And Abimelech said to Abraham, "What is the meaning of these seven ewe lambs that you have set apart?"
30He said, "These seven ewe lambs you will take from my hand, that this may be a witness for me that I dug this well."
