New King James Version (NKJV)
Genesis 21
27 So Abraham took sheep and oxen and gave them to Abimelech, and the two of them made a covenant.
28 And Abraham set seven ewe lambs of the flock by themselves.
29 Then Abimelech asked Abraham, "What is the meaning of these seven ewe lambs which you have set by themselves?"
30 And he said, "You will take these seven ewe lambs from my hand, that they may be my witness that I have dug this well."
31 Therefore he called that place Beersheba, because the two of them swore an oath there.
32 Thus they made a covenant at Beersheba. So Abimelech rose with Phichol, the commander of his army, and they returned to the land of the Philistines.
33 Then Abraham planted a tamarisk tree in Beersheba, and there called on the name of the Lord, the Everlasting God.
34 And Abraham stayed in the land of the Philistines many days.
Genesis 22
1 Now it came to pass after these things that God tested Abraham, and said to him, "Abraham!" And he said, "Here I am."
2 Then He said, "Take now your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you."
3 So Abraham rose early in the morning and saddled his donkey, and took two of his young men with him, and Isaac his son; and he split the wood for the burnt offering, and arose and went to the place of which God had told him.
