Matthew 5:31-35 New American Standard Bible (NASB)

31. "It was said, 'Whoever sends his wife away, let him give her a certificate of divorce';

32. but I say to you that everyone who divorces his wife, except for the reason of unchastity, makes her commit adultery; and whoever marries a divorced woman commits adultery.

33. "Again, you have heard that the ancients were told, 'You shall not make false vows, but shall fulfill your vows to the Lord.'

34. But I say to you, make no oath at all, either by heaven, for it is the throne of God,

35. or by the earth, for it is the footstool of His feet, or by Jerusalem, for it is the city of the great King.
