1 Chronicles 19:13

וְאֵת יֶתֶר הָעָם נָתַן בְּיַד אַבְשַׁי אָחִיו וַיַּעַרְכוּ לִקְרַאת בְּנֵי עַמּֽוֹן

And the rest of the people he committed into the hand of Abishai his brother, and they put themselves in array against the children of Ammon.

וַיֹּאמֶר אִם־תֶּחֱזַק מִמֶּנִּי אֲרָם וְהָיִיתָ לִּי לִתְשׁוּעָה וְאִם־בְּנֵי עַמּוֹן יֶֽחֶזְקוּ מִמְּךָ וְהוֹשַׁעְתִּֽיךָ

And he said: ‘If the Arameans be too strong for me, then thou shalt help me; but if the children of Ammon be too strong for thee, then I will help thee.

וַיִּגַּשׁ יוֹאָב וְהָעָם אֲשֶׁר־עִמּוֹ לִפְנֵי אֲרָם לַמִּלְחָמָה וַיָּנוּסוּ מִפָּנָֽיו

So Joab and the people that were with him drew nigh unto the battle to meet the Arameans; and they fled before him.

וּבְנֵי עַמּוֹן רָאוּ כִּי־נָס אֲרָם וַיָּנוּסוּ גַם־הֵם מִפְּנֵי אַבְשַׁי אָחִיו וַיָּבֹאוּ הָעִירָה וַיָּבֹא יוֹאָב יְרוּשָׁלִָֽם

And when the children of Ammon saw that the Arameans were fled, they likewise fled before Abishai his brother, and entered into the city. Then Joab came to Jerusalem.
