Just Yes or No

You have also heard that our ancestors were told: You must not break your vows; you must carry out the vows you make to the LORD.
But I say, do not make any vows! Do not say: By heaven! because heaven is God’s throne.
And do not say: By the earth! because the earth is his footstool. And do not say: By Jerusalem! for Jerusalem is the city of the great King.
Do not even say: By my head! for you can’t turn one hair white or black.
Just say a simple: Yes, I will, or No, I won’t. Anything beyond this is from the evil one. Matthew 5:33-37 NLT
