Genesis 21:31-34 Young's Literal Translation Of The Holy Bible (YLT98)

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 tamarisk 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.
