'Servant' in the Bible

‘O Lord God, You have begun to show Your servant Your greatness and Your strong hand; for what god is there in heaven or on earth who can do such works and mighty acts as Yours?

but the seventh day is a sabbath of the Lord your God; in it you shall not do any work, you or your son or your daughter or your male servant or your female servant or your ox or your donkey or any of your cattle or your sojourner who stays with you, so that your male servant and your female servant may rest as well as you.

‘You shall not covet your neighbor’s wife, and you shall not desire your neighbor’s house, his field or his male servant or his female servant, his ox or his donkey or anything that belongs to your neighbor.’

then you shall take an awl and pierce it through his ear into the door, and he shall be your servant forever. Also you shall do likewise to your maidservant.

“You shall not oppress a hired servant who is poor and needy, whether he is one of your countrymen or one of your aliens who is in your land in your towns.

So Moses the servant of the Lord died there in the land of Moab, according to the word of the Lord.
