'Subjects' in the Bible

He also defeated the Moabites, and they became David’s subjects and brought tribute.

Then he placed garrisons in Aram of Damascus, and the Arameans became David’s subjects and brought tribute. The Lord made David victorious wherever he went.

When Hadadezer’s subjects saw that they had been defeated by Israel, they made peace with David and became his subjects. After this, the Arameans were never willing to help the Ammonites again.
