1 Chronicles 19:10-12

New Century Version

¹⁰ Joab saw that there were enemies both in front of him and behind him. So he chose some of the best soldiers of Israel and sent them out to fight the Arameans. ¹¹ Joab put the rest of the army under the command of Abishai, his brother. Then they went out to fight the Ammonites. ¹² Joab said to Abishai, “If the Arameans are too strong for me, you must help me. Or, if the Ammonites are too strong for you, I will help you.
