Matthew 5:34 WEB

³²  but I tell you that whoever puts away his wife, except for the cause of sexual immorality, makes her an adulteress; and whoever marries her when she is put away commits adultery.

³³  'Again you have heard that it was said to them of old time, 'You shall not make false vows, but shall perform to the Lord your vows,'

³⁴  but I tell you, don't swear at all: neither by heaven, for it is the throne of God;

³⁵  nor by the earth, for it is the footstool of his feet; nor by Jerusalem, for it is the city of the great King.

³⁶  Neither shall you swear by your head, for you can't make one hair white or black.
