2 Samuel 10:19

19 And all the kings, that were in help of Hadadezer, saw that they were overcome of Israel, and they made peace with Israel, and served them; and the Syrians dreaded to give (more) help to the sons of Ammon. (And when all the kings, who were subject to Hadadezer, saw that they were overcome by Israel, they made peace with Israel, and served them; and from then on the Syrians were afraid to give any more help to the Ammonites.)

2 Samuel 10:19 Meaning and Commentary

2 Samuel 10:19

And when all the kings [that were] servants to Hadarezer
That were subject to him, and at his beck and command, at least were hired by him into his service:

saw that they were smitten before Israel;
could not stand their ground against them, being too powerful for them;

they made peace with Israel, and served them;
became tributaries to them, whereby the promise of the land of Canaan made to Abraham and his seed, as reaching to the river Euphrates, had its accomplishment, ( Genesis 15:18 ) ;

so the Syrians feared to help the children of Ammon any more;
who standing by themselves, they were soon and easily conquered by David's forces, as recorded in the following chapters.

(And the Syrians fled from the Israelites; and David killed of those Syrians the men in seven hundred chariots, and forty thousand horsemen; and he struck down Shobach, the leader of the cavalry, or of the army, who died on the battlefield.)
