'Serve' in the Bible
Samuel spoke to all the house of Israel, saying, "If you do return to Yahweh with all your heart, then put away the foreign gods and the Ashtaroth from among you, and direct your hearts to Yahweh, and serve him only; and he will deliver you out of the hand of the Philistines."
Let it be, when these signs have come to you, that you do as occasion shall serve you; for God is with you.
Then Nahash the Ammonite came up, and encamped against Jabesh Gilead: and all the men of Jabesh said to Nahash, "Make a covenant with us, and we will serve you."
They cried to Yahweh, and said, 'We have sinned, because we have forsaken Yahweh, and have served the Baals and the Ashtaroth: but now deliver us out of the hand of our enemies, and we will serve you.'
If you will fear Yahweh, and serve him, and listen to his voice, and not rebel against the commandment of Yahweh, and both you and also the king who reigns over you are followers of Yahweh your God, [well]:
Samuel said to the people, "Don't be afraid. You have indeed done all this evil; yet don't turn aside from following Yahweh, but serve Yahweh with all your heart.
Only fear Yahweh, and serve him in truth with all your heart; for consider how great things he has done for you.
If he be able to fight with me, and kill me, then will we be your servants; but if I prevail against him, and kill him, then you will be our servants, and serve us."
Now therefore, please let my lord the king hear the words of his servant. If it is so that Yahweh has stirred you up against me, let him accept an offering. But if it is the children of men, they are cursed before Yahweh; for they have driven me out this day that I shouldn't cling to Yahweh's inheritance, saying, 'Go, serve other gods!'
