Thematic Bible: Between abraham and abimelech, concerning wells of water

Then Abraham complained to Abimelech on account of the well of water that servants of Abimelech had seized. And Abimelech said, "I do not know who did this thing, neither did you tell me, nor have I heard [of it] except for today." And Abraham took sheep and cattle and gave [them] to Abimelech. And the two of them {made} a covenant. read more.
Then Abraham set [off] seven ewe-lambs of the flock by themselves. And Abimelech said to Abraham, "What [is the meaning of] these seven ewe-lambs that you have set [off] by themselves?" And he said, "You shall take the seven ewe-lambs from my hand {as proof on my behalf} that I dug this well." Therefore that place is called Beersheba, because there the two of them swore an oath. And they {made} a covenant at Beersheba. And Abimelech, and Phicol his army commander stood and returned to the land of the Philistines.
