Matthew 5:33-34, 37
Matthew 5:33-34 NASB1995
“Again, you have heard that the ancients were told, ‘YOU SHALL NOT MAKE FALSE VOWS, BUT SHALL FULFILL YOUR VOWS TO THE LORD.’ But I say to you, make no oath at all, either by heaven, for it is the throne of God
Matthew 5:37 NASB1995
But let your statement be, ‘Yes, yes’ or ‘No, no’; anything beyond these is of evil.
