International Standard Version When the Ammonites saw the Arameans retreating, they also retreated from Joab's brother Abishai back to the city and Joab left for Jerusalem.
American Standard Version And when the children of Ammon saw that the Syrians were fled, they likewise fled before Abishai his brother, and entered into the city. Then Joab came to Jerusalem.
Young's Literal Translation and the sons of Ammon have seen that Aram hath fled, and they flee -- they also -- from the face of Abishai his brother, and go in to the city. And Joab cometh in to Jerusalem.
