'Serveth' in the Bible

and goeth and serveth other gods, and boweth down to them, either to the sun or to the moon, or to the whole host of heaven, which I have not commanded;

But the nation that bringeth its neck under the yoke of the king of Babylon and serveth him, will I let remain still in its own land, saith Jehovah; and they shall till it, and dwell therein.

And they shall be unto me a peculiar treasure, saith Jehovah of hosts, in the day that I prepare; and I will spare them as a man spareth his own son that serveth him.

And ye shall return and discern between the righteous and the wicked, between him that serveth God and him that serveth him not.
