But above all things, my brethren, swear not, neither by heaven, neither by the earth, neither by any other oath: but let your yea be yea; and your nay, nay; lest you fall under judgment.
All Commentaries on James 5:12 Go To James 5
George Leo Haydock
AD 1849
But above all things swear not, this earnest admonition is against all kind of oaths in common conversation, (not against oaths made on just and necessary occasions) and in the very same words, as our blessed Savior warned all people against this sin of swearing. (Matthew 5) How unaccountably is this commandment of God contemned? And what a dreadful account will some day be exacted for so many oaths, curses, and blasphemies, which are now so common, that we may rather wonder at the patience of God and that already exemplary punishments have not fallen upon whole cities and kingdoms for this continued profanation of the holy name of God?
St. James here repeats the injunctions of our Saviour, not to swear al all. (Matthew v. 34.) See the annotations in that place.
