2 Samuel 10:12 Meaning

10And the rest of the people he delivered into the hand of Abishai his brother, that he might put them in array against the children of Ammon.

11And he said, If the Syrians be too strong for me, then thou shalt help me: but if the children of Ammon be too strong for thee, then I will come and help thee.

12Be of good courage, and let us play the men for our people, and for the cities of our God: and the LORD do that which seemeth him good.

13And Joab drew nigh, and the people that were with him, unto the battle against the Syrians: and they fled before him.

14And when the children of Ammon saw that the Syrians were fled, then fled they also before Abishai, and entered into the city. So Joab returned from the children of Ammon, and came to Jerusalem.
