'Serve' in the Bible

But it came to pass, when the judge was dead, that they turned back, and dealt more corruptly than their fathers, in following other gods to serve them, and to bow down unto them; they ceased not from their doings, nor from their stubborn way.

And Gaal the son of Ebed said, Who is Abimelech, and who is Shechem, that we should serve him? is not he the son of Jerubbaal? and Zebul his officer? serve ye the men of Hamor the father of Shechem: but why should we serve him?

Then said Zebul unto him, Where is now thy mouth, that thou saidst, Who is Abimelech, that we should serve him? is not this the people that thou hast despised? go out now, I pray, and fight with them.
