Matthew Poole and continuators on Matthew 5:37

37 But let your communication be Yea, Yea, Nay, Nay, for whatsoever is more than these cometh of evil.

St. Iames saith much the same, Ia. 5.12. Let your ordinary Discourse in the World be meer Affirmations, or Denials of things in Terms, or Phrases of the same import, with Yea and Nay, tho you do not always use those Terms: Let Forms of Swearing, be preserved for special times, when the Providence of God calls to you for them to determine strife, and make some weighty matters which you assert credible unto others who will not take your bare Assertions, have such a Reverence for the Name of God, as not to use it for every trifle, and let not my Ordinance for the end of Strife be made of no use, by your common use of the Name of God, for in ordinary Discourse, and common Talk, whatsoever is more than bare Affirmations and Denials, cometh of an evil Heart or from the Devil, or from the Corruption of other mens Hearts. Some would make the Communication mentioned here, to be understood as if it were Conversation, or your ways of dealing with Men be plain without Fraud, and Guile, and so think our Saviour here strikes at the Root, and cause of so much idle and vain Swearing, viz. the common Falshood, Frauds, and Cosenages of Men in their dealings; but it seemeth hard so to interpret [non-Latin text not transcribed] in this place. Our Saviour especially being speaking concerning Words and Forms of Speech.
