33. You know that our ancestors were told, “Don't use the Lord's name to make a promise unless you are going to keep it.”
34. But I tell you not to swear by anything when you make a promise! Heaven is God's throne, so don't swear by heaven.
35. The earth is God's footstool, so don't swear by the earth. Jerusalem is the city of the great king, so don't swear by it.
36. Don't swear by your own head. You cannot make one hair white or black.
37. When you make a promise, say only “Yes” or “No”. Anything else comes from the devil.
