'Serves' in the Bible

These [were] those counted of the clans of the descendants of Gershon, everyone who serves in the tent of assembly whom Moses and Aaron mustered according to {the command} of Yahweh.

"They will be mine," says Yahweh of hosts, "on the day that I [am] acting, [my] treasured possession. I will have compassion on them as a man has compassion on his son who serves him.

You will return and see [the difference] between [the] righteous and [the] wicked, between [the one who] serves God and the one who does not serve him.
