Parallel
2 Samuel 10:19
Brenton's English Septuagint · Berean Standard Bible
And all the kings the servants of Adraazar saw that they were put to the worse before Israel, and they went over to Israel, and served them: and Syria was afraid to help the children of Ammon any more.
When all the kings who were subject to Hadadezer saw that they had been defeated by Israel, they made peace with Israel and became subject to them. So the Arameans were afraid to help the Ammonites anymore.
