Genesis 29:4

4. My brethren, whence be ye? The great frankness of that age appears in this manner of meeting together; for, though the fraternal name is often abused by dishonest and wicked men, it is yet not to be doubted that friendly intercourse was then more faithfully cultivated than it is now. This was the reason why Jacob salutes unknown men as brethren, undoubtedly according to received custom. Frugality also is apparent, in that Rachel sometimes pays attention to the flock; for, since Laban abounds with servants, how does it happen that he employs his own daughter in a vile and sordid service, except that it was deemed disgraceful to educate children in idleness, softness, and indulgence? Whereas, on the contrary, at this day, since ambition, pride, and refinement, have rendered manners effeminate, the care of domestic concerns is held in such contempt, that women, for the most part, are ashamed of their proper office. It followed, from the same purity of manners which has been mentioned, that Jacob ventured so unceremoniously to kiss his cousin; for much greater liberty was allowed in their chaste and modest mode of living. In our times, impurity and ungovernable lusts are the cause why not only kisses are suspected, but even looks are dreaded; and not unjustly, since the world is filled with every kind of corruption, and such perfidy prevails, that the intercourse between men and women is seldom conducted with modesty: wherefore, that ancient simplicity ought to cause us deeply to mourn; so that this vile corruption into which the world has fallen may be distasteful to us, and that the contagion of it may not affect us and our families. The order of events, however, is inverted in the narration of Moses; for Jacob did not kiss Rachel till he had informed her that he was her relative. Hence also his weeping; for, partly through joy, partly through the memory of his father’s house, and through natural affection, he burst into tears.
