1 Chronicles 18:12

Moreover Abishai ... — Heb., And Abishai son of Zeruiah had smitten Edom in the Valley of Salt, eighteen thousand.

In Samuel we read something quite different: “And David made a name, when he returned from his smiting Aram.” “Aram” should be read Edom, as the LXX., Syriac, and Arabic have it. Perhaps, also, the text of Samuel is further corrupted. (Comp. 1 Kings 11:15. and Psalms 60, title.) From a comparison of the three passages it appears that Edom took advantage of David’s absence to invade Judah, whereupon the king detached a column of his forces, and sent them south under Joab and Abishai to repulse the new enemy.

Valley of salt. — 2 Kings 14:7.
