'Serve' in the Bible

Are they not all ministering spirits sent out to serve those who are going to inherit salvation?

For God is not unjust; He will not forget your work and the love you showed for His name when you served the saints—and you continue to serve them.

Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount.

How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?

Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:

We have an altar, whereof they have no right to eat which serve the tabernacle.
