1 Chronicles 19:10-12

10When Joab saw he was under attack in front and behind, he took the select troops of Israel and organized them for combat against the Arameans.

11He put his brother Abishai in charge of the rest of the troops. They organized for combat against the Ammonites.

12Joab said, “If the Arameans are too strong for my ⌞troops⌟, be ready to help me. And if the Ammonites are too strong for your ⌞troops⌟, I’ll help you.
