2 Samuel 8:13

And David gat him a name when he returned from smiting of the Syrians in the valley of salt, being eighteen thousand men.

Returned from smiting of the Syrians, х 'et (H854) 'Araam (H758). Instead of Syrians, the Septuagint version has Edomites, the Septuagint having read 'Edowm (H123) (1 Chronicles 18:12), which is the true, reading, as is evident from 2 Samuel 8:14 (see Davidson's 'Hebrew Text of the Old Testament,' in loco.)] This conquest, made by the army of David, was due to the skillful generalship and gallantry of Ahishai and Joab (1 Chronicles 18:12: cf. Psalms 60:1, title). The valley was the ravine of Salt, in the neighbourhood of Sela, at the foot of Jebel Usdum (the Ghor, or upper part of the Arabah), adjoining the Salt Mountain, at the southwestern extremity of the Dead Sea, separating the ancient territories of Judah and Edom (Robinson's, 'Biblical Researchers,' 2:, p. 283; Porter's 'Handbook,' p. 61; Stanley, 'Sinai and Palestine,' p. 478).
