'Serving' in the Bible

Then Elkanah went back home to Ramah. But the boy was serving the Lord under the supervision of Eli the priest.

Now the boy Samuel continued serving the Lord under Eli's supervision. Word from the Lord was rare in those days; revelatory visions were infrequent.

Be strong and act like men, you Philistines, or else you will wind up serving the Hebrews the way they have served you! Act like men and fight!"

If you fear the Lord, serving him and obeying him and not rebelling against what he says, and if both you and the king who rules over you follow the Lord your God, all will be well.

So Achish summoned David and said to him, "As surely as the Lord lives, you are an honest man, and I am glad to have you serving with me in the army. I have found no fault with you from the day that you first came to me until the present time. But in the opinion of the leaders, you are not reliable.
