Context Reading
29Abimelech said to Abraham, “What do these seven ewe lambs, which you have set by themselves, mean?” 30He said, “You shall take these seven ewe lambs from my hand, that it may be a witness to me, that I have dug this well.” 31Therefore he called that place Beersheba,because they both swore an oath there. 32So they made a covenant at Beersheba. Abimelech rose up with Phicol, the captain of his army, and they returned into the land of the Philistines. 33Abraham planted a tamarisk tree in Beersheba, and there he called on the name of Yahweh, the Everlasting God.
