'Serve' in the Bible

Then Gaal son of Ebed said, "Who [is] Abimelech, and who [are we of] Shechem that we should serve him? Is he not the son of Jerub-Baal, and [is not] Zebul his chief officer? Serve the men of Hamor the father of Shechem. Why should we serve him?

And Zebul said to him, "Where then {is your boast}, [you] who said, 'Who [is] Abimelech that we should serve him?' [Is] this not the army that you rejected? Please, go out now and fight against them."

And again, the {Israelites} did evil in the eyes of Yahweh. They served the Baals, the Ashtaroth, the gods of Aram, Sidon, Moab, and the gods of the {Ammonites} and Philistines; they abandoned Yahweh and did not serve him.
