But I say unto you, Swear not at all; neither by heaven; for it is God's throne:
All Commentaries on Matthew 5:34 Go To Matthew 5
George Leo Haydock
AD 1849
Swear not at all. We must not imagine that here are forbidden all oaths, where there is a just and necessary cause of calling God to witness. An oath on such an occasion is an act of justice and religion. Here are forbidden unnecessary oaths in common discourse, by which the sacred name of God, which never ought to be pronounced without reverence and respect, is so frequently and scandalously profaned. (Witham)
'Tis not forbidden to swear in truth, justice and judgment; to the honour of God, or our own or neighbours' just defence; but only to swear rashly, or profanely, in common discourse, and without necessity. (Challoner)
