Verse 4 Referring to a regulation of the Jewish code, recorded Deuteronomy 24:1-4.

Hence it is often necessary to restrain and regulate what it is impossible to prevent. Mark 10:7,8. The words And said are to be understood at the commencement of these verses; for the verses are quoted from Genesis 2:24, as the language used by Jehovah, expressive of his original design in regard to the sexes. The Savior resumes his own remarks at Mark 10:9. The argument is, that the law which the Pharisees quoted was a municipal regulation, adapted to circumstances, but that for the true principle which was to decide the question, in a moral point of view, they must go back to the declaration of God himself, made at the original institution of the ordinance of marriage.--Twain; two.
