'Served' in the Bible

Son of man, Nebuchadrezzar king of Babylon caused his army to do hard service against Tyre; every head was made bald, and every shoulder was peeled: yet had he from Tyre no wages, nor his army, for the service that he had served against it.

I have given him the land of Egypt for his labour wherewith he served against it, because they wrought for me, saith the Lord Jehovah.
