'Serve' in the Bible

Then Jesus *said to him, “Go, Satan! For it is written, ‘You shall worship the Lord your God, and serve Him only.’”

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

just as the Son of Man did not come to be served, but to serve, and to give His life a ransom for many.”
