Matthew 5:31-33

New Revised Standard Version, Anglicised Catholic Edition

Concerning Divorce

³¹ ‘It was also said, “Whoever divorces his wife, let him give her a certificate of divorce.” ³² But I say to you that anyone who divorces his wife, except on the ground of unchastity, causes her to commit adultery; and whoever marries a divorced woman commits adultery.

Concerning Oaths

³³ ‘Again, you have heard that it was said to those of ancient times, “You shall not swear falsely, but carry out the vows you have made to the Lord.”
