Well of the oath, or well of seven, a well dug by Abraham, and so named because he and Abimelech here entered into a compact (Gen. 21:31). On re-opening it, Isaac gave it the same name (Gen. 26:31-33). It was a favourite place of abode of both of these patriarchs (21:33-22:1, 19; 26:33; 28:10). It is mentioned among the “cities” given to the tribe of Simeon (Josh. 19:2; 1 Chr. 4:28). From Dan to Beersheba, a distance of about 144 miles (Judg. 20:1; 1 Chr. 21:2; 2 Sam. 24:2), became the usual way of designating the whole Promised Land, and passed into a proverb. After the return from the Captivity the phrase is narrowed into “from Beersheba unto the valley of Hinnom” (Neh. 11:30). The kingdom of the ten tribes extended from Beersheba to Mount Ephraim (2 Chr. 19:4). The name is not found in the New Testament. It is still called by the Arabs Bir es-Seba, i.e., “well of the seven”, where there are to the present day two principal wells and five smaller ones. It is nearly midway between the southern end of the Dead Sea and the Mediterranean.
Beer-Sheba
Abraham and Abimelech settle a quarrel over a well, swear an oath, and name the place Beersheba. Then Abraham “planted a grove in Beersheba, and called there on the name of the LORD, the everlasting God” (Genesis 21:33). Later it appears in Judah’s and Simeon’s lists of towns. Amos warns the people not to “pass not to Beersheba,” treating its worship as empty. And when Elijah collapses under a juniper tree further south, an angel touches him and says, “Arise and eat.” Genesis 21:22-34 tells how the place got its name.
10 verses
Genesis
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.
Joshua
This is the inheritance of the tribe of the children of Judah according to their families.
And Hazarshual, and Beersheba, and Bizjothjah,
And they had in their inheritance Beersheba, or Sheba, and Moladah,
Out of the portion of the children of Judah was the inheritance of the children of Simeon: for the part of the children of Judah was too much for them: therefore the children of Simeon had their inheritance within the inheritance of them.
1 Kings
And as he lay and slept under a juniper tree, behold, then an angel touched him, and said unto him, Arise and eat.
And the angel of the LORD came again the second time, and touched him, and said, Arise and eat; because the journey is too great for thee.
Amos
But seek not Bethel, nor enter into Gilgal, and pass not to Beersheba: for Gilgal shall surely go into captivity, and Bethel shall come to nought.
