'Undermining' in the Bible

Then the officials told the king, "Let this man be put to death because he's undermining the efforts of the soldiers who remain in this city and that of all the people by speaking words like these to them. Indeed, this man is not seeking the well-being of this people, but rather their harm."

They have strayed from the truth by saying that the resurrection has already occurred, and they are undermining some people's faith.
