Matthew 5:33-37

“Again, your ancestors were taught, ‘Never swear an oath that you don’t intend to keep, but keep your vows to the Lord God.’ However, I say to you, don’t bind yourself by taking an oath at all. Don’t swear by heaven, for heaven is where God’s throne is placed. Don’t swear an oath by the earth, because it is the rug under God’s feet, and not by Jerusalem, because it is the city of the Great King. And why would you swear by your own head, because it’s not in your power to turn a single hair white or black? But just let your words ring true. A simple ‘Yes’ or ‘No’ will suffice. Anything beyond this springs from a deceiver.
