Genesis 21:29-31 Living Bible (TLB)
28-29 But when he took seven ewe lambs and set them off by themselves, the king inquired, “Why are you doing that?”
30 And Abraham replied, “They are my gift to you as a public confirmation that this well is mine.”
31 So from that time on the well was called Beer-sheba (“Well of the Oath”), because that was the place where they made their covenant.
Genesis 21:29-31 New International Version (NIV)
29 and Abimelek asked Abraham, “What is the meaning of these seven ewe lambs you have set apart by themselves?”
30 He replied, “Accept these seven lambs from my hand as a witness that I dug this well.”
31 So that place was called Beersheba,[a] because the two men swore an oath there.
