'Serve' in the Bible

For God, whom I serve with my spirit in the gospel of his Son, is my witness, how constantly I make mention of you,

But now we have been released from the law, [because we] have died [to that] by which we were bound, so that we may serve in newness of the Spirit and not in oldness of the letter [of the law].

not by works but by the one who calls--it was said to her, "The older will serve the younger,"

For they were pleased [to do so], and they are obligated to them. For if the Gentiles have shared in their spiritual [things], they ought also to serve them in material [things].

For such people do not serve our Lord Christ, but their own stomach, and by smooth speech and flattery they deceive the hearts of the unsuspecting.
