'Bond servant' in the Bible

He said, "Now also let it be according to your words: he with whom it is found will be my bondservant; and you will be blameless."

He said, "Far be it from me that I should do so. The man in whose hand the cup is found, he will be my bondservant; but as for you, go up in peace to your father."

Now therefore, please let your servant stay instead of the boy, a bondservant to my lord; and let the boy go up with his brothers.
