2 Samuel 10:9-11

New International Version - UK

⁹ Joab saw that there were battle lines in front of him and behind him; so he selected some of the best troops in Israel and deployed them against the Arameans. ¹⁰ He put the rest of the men under the command of Abishai his brother and deployed them against the Ammonites. ¹¹ Joab said, ‘If the Arameans are too strong for me, then you are to come to my rescue; but if the Ammonites are too strong for you, then I will come to rescue you.
