Swearing to a falsehood. Perjury is never permissible even though one swears to the truth of only a slight lie. Even in this case the sin is serious, because great dishonor is shown to God be calling upon him to witness to the truth of what is known to be false. (Etym. Latin periurium, false oath, broken oath.)
