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.]
36 And do not swear by your head, for you are not able to make a single hair white or black.
37 Let your Yes be simply Yes, and your No be simply No; anything more than that comes from the evil one. [Lev. 19:12; Num. 30:2; Deut. 23:21.]
