'Bondmen' in the Bible

For many nations and great kings shall make bondmen of them, even of them; and I will recompense them according to their deeds, and according to the work of their hands.

that every man should let his man-servant, and every man his maid-servant, that is a Hebrew or a Hebrewess, go free; that none should make bondmen of them, to wit , of a Jew his brother.

And all the princes and all the people obeyed, that had entered into the covenant, that every one should let his man-servant, and every one his maid-servant, go free, that none should make bondmen of them any more; they obeyed, and let them go:

But afterwards they turned, and caused the bondmen and the bondmaids whom they had let go free, to return, and brought them into subjection for bondmen and for bondmaids.

Thus saith the LORD, the God of Israel; I made a covenant with your fathers in the day that I brought them forth out of the land of Egypt, out of the house of bondmen, saying,

but ye have turned and profaned my name, and caused every man his bondman, and every man his bondmaid, whom ye had set at liberty at their pleasure, to return, and ye have brought them into subjection, to be unto you for bondmen and for bondmaids.
