“But let your communication bee Yea, yea: Nay, nay: For whatsoeuer is more then these, commeth of euill.”
1611 King James Version (KJV)
5:37 Let your conversation be yea, yea; nay, nay - That is, in your common discourse, barely affirm or deny.
Mt 5:37 Let your communication be, Yea, yea. All foolish appeals are forbidden. A simple statement is all Christ permits. Whatsoever is more than these cometh of evil. Indeed, it makes one doubt the truth of him who was to confirm every assertion by oath.
