1 Chronicles 19:9-12

MSB(i) 9 The Ammonites marched out and arrayed themselves for battle at the entrance to the city, while the kings who had come stayed by themselves in the open country. 10 When Joab saw the battle lines before him and behind him, he selected some of the best men of Israel and arrayed them against the Arameans. 11 And he placed the rest of the forces under the command of his brother Abishai, who arrayed them against the Ammonites. 12 “If the Arameans are too strong for me,” said Joab, “then you will come to my rescue. And if the Ammonites are too strong for you, then I will come to your rescue.
