Shmuel Bais 10:18-19

Orthodox Jewish Bible

¹⁸ And the Syrians fled before Yisroel; and Dovid slaughtered the men of seven hundred chariots of the Syrians, and forty elef parashim, and struck down Shovach the Sar of his Tzeva (army), who died there.

¹⁹ And when all the melachim that were avadim (vassals) to Hadadezer saw that they were defeated before Yisroel, they made shalom with Yisroel, and served them. So the Syrians feared to help the Bnei Ammon any more.
