'Serve' in the Bible

To grant us that we, being rescued from the hand of our enemies,Might serve Him without fear,

Jesus answered him, “It is written, ‘You shall worship the Lord your God and serve Him only.’”

Blessed are those slaves whom the master will find on the alert when he comes; truly I say to you, that he will gird himself to serve, and have them recline at the table, and will come up and wait on them.

No servant can serve two masters; for either he will hate the one and love the other, or else he will be devoted to one and despise the other. You cannot serve God and wealth.”

But will he not say to him, ‘Prepare something for me to eat, and properly clothe yourself and serve me while I eat and drink; and afterward you may eat and drink’?
