Genesis 21:32 YLT

³⁰  And he saith, 'For -- the seven lambs thou dost accept from my hand, so that it becometh a witness for me that I have digged this well;'

³¹  therefore hath he called that place 'Beer-Sheba,' for there have both of them sworn.

³²  And they make a covenant in Beer-Sheba, and Abimelech riseth -- Phichol also, head of his host -- and they turn back unto the land of the Philistines;

³³  and 'Abraham' planteth a tamarask in Beer-Sheba, and preacheth there in the name of Jehovah, God age-during;

³⁴  and Abraham sojourneth in the land of the Philistines many days.
