31. It has also been said, Whoever divorces his wife must give her a certificate of divorce.
32. But I tell you, Whoever dismisses and repudiates and divorces his wife, except on the grounds of unfaithfulness (sexual immorality), causes her to commit adultery, and whoever marries a woman who has been divorced commits adultery. [Deut. 24:1-4.]
33. Again, you have heard that it was said to the men of old, You shall not swear falsely, but you shall perform your oaths to the Lord [as a religious duty].
34. But I tell you, Do not bind yourselves by an 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. [Ps. 48:2; Isa. 66:1.]
