'Served' in the Bible

Son of man, Nebuchadnezzar king of Babylon caused his army to serve a great service against Tyre: every head was made bald, and every shoulder was worn; yet had he no wages, nor his army, from Tyre, for the service that he had served against it.

I have given him the land of Egypt as his recompense for which he served, because they worked for me, says the Lord Yahweh.
