Matthew 19:5

καὶ εἶπεν : God said, though the words as they stand in Gen. may be a continuation of Adam's reflections, or a remark of the writer. ἕνεκεν τούτου : connected in Gen. with the story of the woman made from the rib of the man, here with the origin of sex. The sex principle imperiously demands that all other relations and ties, however intimate and strong, shall yield to it. The cohesion this force creates is the greatest possible. οἱ δύο : these words in the Sept [109] have nothing answering to them in the Hebrew, but they are true to the spirit of the original. εἰς σάρκα μίαν : the reference is primarily to the physical fleshly unity. But flesh in Hebrew thought represents the entire man, and the ideal unity of marriage covers the whole nature. It is a unity of soul as well as of body: of sympathy, interest, purpose.
