Genesis 26:19-25

19Then Isaac’s servants dug in the valley and found a well of fresh water1 there. 20But the herdsmen of Gerar quarreled with Isaac’s herdsmen and said, “The water is ours!” So he named the well Esek,2 because they contended with him.

21Then they dug another well and quarreled over that one also; so he named it Sitnah.3

22He moved on from there and dug another well, and they did not quarrel over it. He named it Rehoboth4 and said, “At last the LORD has made room for us, and we will be fruitful in the land.”

23From there Isaac went up to Beersheba, 24and that night the LORD appeared to him and said, “I am the God of your father Abraham. Do not be afraid, for I am with you. I will bless you and multiply your descendants for the sake of My servant Abraham.”

25So Isaac built an altar there and called on the name of the LORD, and he pitched his tent there. His servants also dug a well there.
