John Lightfoot on Matthew 19:3

[Is it lawful for a man to put away his wife for every cause?] Of the causes, ridiculous (shall I call them?) or wicked, for which they put away their wives, we have spoke at chapter 5:31. We will produce only one example here; "When Rabh went to Darsis ('whither,' as the Gloss saith, 'he often went'), he made a public proclamation, What woman will have me for a day? Rabh Nachman, when he went to Sacnezib, made a public proclamation, What woman will have me for a day?" The Gloss is, "Is there any woman who will be my wife while I tarry in this place?"

The question here propounded by the Pharisees was disputed in the schools, and they divided into parties concerning it, as we have noted before. For the school of Shammai permitted not divorces, but only in the case of adultery; the school of Hillel, otherwise.
