1 Chronicles 19:11

7So they hired for themselves thirty-two thousand chariots, and the king of Maacah with his people, who came and encamped near Medeba. The children of Ammon gathered themselves together from their cities, and came to battle.

8When David heard of it, he sent Joab with all the army of the mighty men.

9The children of Ammon came out, and put the battle in array at the gate of the city; and the kings who had come were by themselves in the field.

10Now when Joab saw that the battle was set against him before and behind, he chose some of all the choice men of Israel, and put them in array against the Syrians.

11The rest of the people he committed into the hand of Abishai his brother; and they put themselves in array against the children of Ammon.

12He said, “If the Syrians are too strong for me, then you are to help me; but if the children of Ammon are too strong for you, then I will help you.

13Be courageous, and let’s be strong for our people and for the cities of our God. May the LORD do that which seems good to him.”

14So Joab and the people who were with him came near to the front of the Syrians to the battle; and they fled before him.

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