Matthew 5:33-34, 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.

A simple ‘Yes’ or ‘No’ will suffice. Anything beyond this springs from a deceiver.
