'Serving' in the Bible

There you'll serve gods made by human hands, serving trees and stones that cannot see, hear, eat, nor smell.

He may be following and serving other gods by bowing down to them that is, to the sun, the moon, or to any of the heavenly host (something I did not command).

If a man presumptuously disregards the priest who is serving the LORD your God there or the judge, that person must die so you will purge evil from Israel.
