31It has also been said, ‘Whoever divorces his wife must give her a certificate of divorce.’
32But I tell you that anyone who divorces his wife, except for sexual immorality, brings adultery upon her. And he who marries a divorced woman commits adultery.
33Again, you have heard that it was said to the ancients, ‘Do not break your oath, but fulfill your vows to the Lord.’
34But I tell you not to swear at all: either by heaven, for it is God’s throne;
35or by the earth, for it is His footstool; or by Jerusalem, for it is the city of the great King.
