And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he is. Arise, lift up the lad, and hold him in thine hand; for I will make him a great nation. And God opened her eyes, and she saw a well of water; and she went, and filled the bottle with water, and gave the lad drink. And God was with the lad; and he grew, and dwelt in the wilderness, and became an archer. And he dwelt in the wilderness of Paran: and his mother took him a wife out of the land of Egypt. And it came to pass at that time, that Abimelech and Phichol the chief captain of his host spake unto Abraham, saying, God is with thee in all that thou doest: Now therefore swear unto me here by God that thou wilt not deal falsely with me, nor with my son, nor with my son's son: but according to the kindness that I have done unto thee, thou shalt do unto me, and to the land wherein thou hast sojourned. And Abraham said, I will swear. And Abraham reproved Abimelech because of a well of water, which Abimelech's servants had violently taken away. And Abimelech said, I wot not who hath done this thing: neither didst thou tell me, neither yet heard I of it, but to day. And Abraham took sheep and oxen, and gave them unto Abimelech; and both of them made a covenant. And Abraham set seven ewe lambs of the flock by themselves. And Abimelech said unto Abraham, What mean these seven ewe lambs which thou hast set by themselves? And he said, For these seven ewe lambs shalt thou take of my hand, that they may be a witness unto me, that I have digged this well. Wherefore he called that place Beersheba; because there they sware both of them. Thus they made a covenant at Beersheba: then Abimelech rose up, and Phichol the chief captain of his host, and they returned into the land of the Philistines. And Abraham planted a grove in Beersheba, and called there on the name of the LORD, the everlasting God.
Observe, though Abraham is still in a pilgrimage state, yet in every place, where the Lord manifested himself to him, he sets up his Ebenezer. Isaiah 40:28.
