'Bondman' in the Bible

Jesus answered them, Verily, verily, I say to you, Every one that practises sin is the bondman of sin.

Now the bondman abides not in the house for ever: the son abides for ever.

Verily, verily, I say to you, The bondman is not greater than his lord, nor the sent greater than he who has sent him.

I call you no longer bondmen, for the bondman does not know what his master is doing; but I have called you friends, for all things which I have heard of my Father I have made known to you.

Remember the word which I said unto you, The bondman is not greater than his master. If they have persecuted me, they will also persecute you; if they have kept my word, they will keep also yours.

Simon Peter therefore, having a sword, drew it, and smote the bondman of the high priest and cut off his right ear; and the bondman's name was Malchus.
