'Served' in the Bible

"And the {Israelites} journeyed from [the] wells of Bene-Yaqan [to] Moserah; there Aaron died and was buried, and Eleazar, his son, served as a priest in place of him.

You must completely demolish all [of] the places there where [they] served their gods, [that is], the nations whom you [are] about to dispossess, on the high mountains, and on the hills and under each leafy green tree.

If your relative who is a Hebrew man or a Hebrew woman is sold to you, and [he or she] has served you six years, then in the seventh year you shall send that person [out] {free}.

It shall not be hard in your eyes {when you send him forth free}, because for six years he has served you [worth] twice the wage of a hired worker; and Yahweh your God will bless you {in whatever you will do}.

And they went and served other gods and bowed down to them, gods whom they did not know them and he had not allotted to them.
