'Serve' in the Bible

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

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

But Martha was very busy and distracted with all of her serving responsibilities; and she approached Him and said, “Lord, is it of no concern to You that my sister has left me to do the serving alone? Tell her to help me and do her part.”

Blessed (happy, prosperous, to be admired) are those servants whom the master finds awake and watching when he arrives. I assure you and most solemnly say to you, he will prepare himself to serve, and will have them recline at the table, and will come and wait on them.

No servant can serve two masters; for either he will hate the one and love the other, or he will stand devotedly by the one and despise the other. You cannot serve both God and mammon [that is, your earthly possessions or anything else you trust in and rely on instead of God].”

Will he not instead say to him, ‘Prepare something for me to eat, and appropriately clothe yourself [for service] and serve me while I eat and drink; then afterward you may eat and drink?’
