11 I establish my covenant with you: Never again will all life be destroyed by the waters of a flood; never again will there be a flood to destroy the earth.”
18 On that day the LORD made a covenant with Abram and said, “To your descendants I give this land, from the Wadi of Egypt to the great river, the Euphrates—
14 Any uncircumcised male, who has not been circumcised in the flesh, will be cut off from his people; he has broken my covenant.”
27 So Abraham brought sheep and cattle and gave them to Abimelek, and the two men made a treaty.
32 After the treaty had been made at Beersheba, Abimelek and Phicol the commander of his forces returned to the land of the Philistines.
28 They answered, “We saw clearly that the LORD was with you; so we said, ‘There ought to be a sworn agreement between us’—between us and you. Let us make a treaty with you
44 Come now, let’s make a covenant, you and I, and let it serve as a witness between us.”
