The water that flowed for them on this spot served not only as a relief for their present need, but on this occasion there was revealed to them a well of water, which did not abandon them in all their forty years' wandering, but accompanied them on all their marches. God wrought this great miracle for the merits of the prophetess Miriam, wherefore also it was called "Miriam's Well." But his well dates back to the beginning of the world, for God created it on the second day of the creation, and at one time it was in the possession of Abraham.
It was this same well that Abraham demanded back from Abimelech, king of the Philistines, after the king's servants had violently taken it away. But when Abimelech pretended not to know anything about it, saying, "I wot not who hath done this thing," Abraham said: "Thou and I will send sheep to the well, and he shall be declared the rightful owner of the well, for whose sheep the water will spout forth to water them.
And," continued Abraham, "from that same well shall the seventh generation after me, the wanderers in the desert, draw their supply."
