'Serve' in the Bible

For God [is] not unjust, [so as] to forget your work and the love which you demonstrated for his name [by] having served the saints, and continuing to serve [them].

who serve a sketch and shadow of the heavenly [things], just as Moses was warned [when he] was about to complete the tabernacle, for he says, "See to it that you make everything according to the pattern which was shown to you on the mountain."

how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, cleanse our consciences from dead works to serve [the] living God?

Therefore, [since we] are receiving an unshakable kingdom, let us be thankful, through which let us serve God acceptably, with awe and reverence.

We have an altar from which those who serve in the tabernacle do not have the right to eat.
