John 8:32

And the truth shall make you free. They were affronted at these words, as if he hinted they were slaves, and not a free people. They tell him, therefore, that they were never slaves to any one. They can only pretend this of themselves: for, their forefathers were slaves to the Egyptians, to the Babylonians, &c. and besides they were now the subjects, if not slaves, to the Romans. But Christ speaks of the worst of slaveries, and tells them the such as live in sin, are slaves to sin. (Witham)
