'Serve' in the Bible

Gaal son of Ebed said, "Who is Abimelech and who is Shechem, that we should serve him? Is he not the son of Jerub-Baal, and is not Zebul the deputy he appointed? Serve the sons of Hamor, the father of Shechem! But why should we serve Abimelech?

Zebul said to him, "Where now are your bragging words, 'Who is Abimelech that we should serve him?' Are these not the men you insulted? Go out now and fight them!"

Now this man Micah owned a shrine. He made an ephod and some personal idols and hired one of his sons to serve as a priest.
