'Subservient' in the Bible

He erected garrisons throughout Edom, and all the Edomites became subservient to David, while the LORD gave victory to David wherever he went.

When all the kings who were allied with Hadadezer saw that they had been defeated by Israel, they sought terms of peace with the Israelis and became subservient to them. Furthermore, the Arameans were afraid to help the Ammonites anymore.
