1 Chronicles 18:12-14

King James Version

¹² Moreover Abishai the son of Zeruiah slew of the Edomites in the valley of salt eighteen thousand.

¹³ And he put garrisons in Edom; and all the Edomites became David's servants. Thus the Lord preserved David whithersoever he went.

¹⁴ So David reigned over all Israel, and executed judgment and justice among all his people.
