The well named as “Abraham’s well” was a subject of contention. For a period of time the well was controlled by the Philistines until Isaac his son restored the ownership of the well again. Abraham was to reprove Abimelech (My father is king) over “a well of water” that his men had violently taken away Gen 21:25. This was to be a direct contrast of the reproof of Sarah in Gen 20:9f. In both accounts a rebuke over association with Abraham as the father, and then confirmation that through covenant that Abraham was to be the father through who real righteousness would be established. Abimelech would declare this; “God is with thee in all that thou doest” and confirmed in the ritual of covenant sacrifice of seven lambs, by themselves, that is “God was in them, in all that they were doing” and they did not belong to the Philistines. The meaning of this ritual became enshrined in the place of Beersheba, the well of the seven.
It is most remarkable that Abraham sojourned in the land of the Philistines for many days, and then following these things takes his son to demonstrate the sacrifice of the most remarkable lamb of all time, the lamb of God who came into the world to take away sins, Gen 22.
Jacob left from Beersheba the well of the oath, to go to Haran, Gen 28:10. On arrival he came to a well that was stopped by a great stone, Gen 29:3. Representing national Israel who could not see the manifestation of God because of being bowed down with great traditions. The men were waiting for someone to move the stone, and yet Jacob himself could move the stone when he arrived, having previously made a stone the place of his head, departing alone with just his staff (RSV), Gen 28.
Beersheba became the limits of the land. From Dan to Beersheba, the place of apostacy to being with God in everything that we do. This is the course of all spiritual men.
