'Weakening' in the Bible

The officials then said to the king, “This man ought to die, because he is weakening the morale of the warriors who remain in this city and of all the people by speaking to them in this way. This man is not seeking the well-being of this people, but disaster.”

He considered his own body to be already dead (since he was about 100 years old) and also considered the deadness of Sarah’s womb, without weakening in the faith.
