'Discharged' in the Bible

For the married woman [as an example] is bound and remains bound by law to her husband while he lives; but if her husband dies, she is released and exempt from the law concerning her husband.

But now we have been released from the Law and its penalty, having died [through Christ] to that by which we were held captive, so that we serve [God] in the newness of the Spirit and not in the oldness of the letter [of the Law].
