1 Chronicles 19:15 KJV

13Be of good courage, and let us behave ourselves valiantly for our people, and for the cities of our God: and let the LORD do that which is good in his sight.

14So Joab and the people that were with him drew nigh before the Syrians unto the battle; and they fled before him.

15And when the children of Ammon saw that the Syrians were fled, they likewise fled before Abishai his brother, and entered into the city. Then Joab came to Jerusalem.

16And when the Syrians saw that they were put to the worse before Israel, they sent messengers, and drew forth the Syrians that were beyond the river: and Shophach the captain of the host of Hadarezer went before them.

17And it was told David; and he gathered all Israel, and passed over Jordan, and came upon them, and set the battle in array against them. So when David had put the battle in array against the Syrians, they fought with him.
