Genesis 2:24

Therefore shall a man leave... — These are evidently the words of the narrator. Adam names this new product of creative power, as he had named others, but he knew nothing about young men leaving their father’s house for the wife’s sake. Moreover, in Matthew 19:5, our Lord quotes these words as spoken by God, and the simplest interpretation of this declaration is that the inspired narrator was moved by the Spirit of God to give this solemn sanction to marriage, founded upon Adam’s words. The great and primary object of this part of the narrative is to set forth marriage as a Divine ordinance. The narrator describes Adam’s want, pictures him as examining all animal life, and studying the habits of all creatures so carefully as to be able to give them names, but as returning from his search unsatisfied. At last one is solemnly brought to him who is his counterpart, and he calls her Ishah, his feminine self, and pronounces her to be his very bone and flesh. Upon this, “He who at the beginning made them male and female “pronounced the Divine marriage law that man and wife are one flesh.
