Matthew 5:36

“Again you have heard that it was said to the ancient ones, ‘You shall not make false vows, but shall perform to the Lord your vows,’

but I tell you, don’t swear at all: neither by heaven, for it is the throne of God;

nor by the earth, for it is the footstool of his feet; nor by Jerusalem, for it is the city of the great King.

But let your ‘Yes’ be ‘Yes’ and your ‘No’ be ‘No.’ Whatever is more than these is of the evil one.

“You have heard that it was said, ‘An eye for an eye, and a tooth for a tooth.’

But I tell you, don’t resist him who is evil; but whoever strikes you on your right cheek, turn to him the other also.
