2 Chronicles 19:4
And Jehoshaphat dwelt at Jerusalem: and he went out again through the people from Beersheba to mount Ephraim, and brought them back unto the Lord God of their fathers. (2 Chronicles 19:4)
From Beer-sheba to mount Ephraim.
 That is, all of Judah, from Beersheba in the extreme south to Mt. Ephraim and the borders of Israel on the north. Compare the expression “from Dan even to Beersheba” employed of all Judah and Israel (1 Sam. 3:20; 2 Sam. 3:10; 17:11; 24:2, 15; 1 Kings 4:25; 1 Chron. 21:2; 2 Chron. 30:5).
