'Serve' in the Bible

to grant to us that we, being delivered out of the hand of our enemies, should serve him without fear,

Jesus answered him, "Get behind me Satan! For it is written, 'You shall worship the Lord your God, and you shall serve him only.'"

But Martha was distracted with much serving, and she came up to him, and said, "Lord, don't you care that my sister left me to serve alone? Ask her therefore to help me."

Blessed are those servants, whom the lord will find watching when he comes. Most certainly I tell you, that he will dress himself, and make them recline, and will come and serve them.

No servant can serve two masters, for either he will hate the one, and love the other; or else he will hold to one, and despise the other. You aren't able to serve God and mammon."

and will not rather tell him, 'Prepare my supper, clothe yourself properly, and serve me, while I eat and drink. Afterward you shall eat and drink'?
