1 Chronicles 19:10

So 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.

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

The 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.

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

He 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.

Be 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.”
