Matt. XIX. 1.
“And it came to pass, that when Jesus had finished these sayings, He departed from Galilee, and came into the coasts of Judæa beyond Jordan.”
Having constantly left Judæa on account of the envy of those men, now He frequents it from this time forth, because the passion was to be near at hand; He goes not up, however, unto Jerusalem for a while, but “into the coasts of Judæa.”
“And,” when He had come, “great multitudes followed Him, and He healed them.”
For neither in the teaching by words does He continue always, nor in the wonderful working of signs, but He does now one now the other, variously working the salvation of them that were waiting upon Him and following Him, so as by the miracles to appear, in what He said, a Teacher worthy of belief, and by the teaching of His word to increase the profit from the miracles; and this was to lead them by the hand to the knowledge of God.
But do thou mark, I pray you, this too, how the disciples pass over whole multitudes with one word, not declaring by name each of them that are healed. For they said not, that such a one, and such another, but that many, teaching us to be unostentatious. But Christ healed, benefiting both them, and by them many others. For the healing of these men's infirmity was to others a foundation for the knowledge of God.
But not so to the Pharisees, but even for this self-same thing they become more fierce, and come unto Him tempting Him. For because they could not lay hold of the works that were doing, they propose to Him questions. For they “came unto Him, and tempting Him said, Is it lawful for a man to put away his wife for every cause?”
O folly! They thought to silence Him by their questions, although they had already received certain proof of this power in Him. When at least they argued much about the Sabbath, when they said, “He blasphemes,” when they said, “He has a devil,” when they found fault with His disciples as they were walking in the grain fields, when they argued about unwashen hands, on every occasion having sewed fast their mouths, and shut up their shameless tongue, He thus sent them away. Nevertheless, not even so do they keep off from Him. For such is wickedness, such is envy, shameless and bold; though it be put to silence ten thousand times, ten thousand times does it assault again.
But mark thou, I pray you, their craft also from the form of their question. For neither did they say unto Him, You commanded not to put away a wife, for indeed He had already discoursed about this law; but never theless they made no mention of those words; but took occasion from hence, and thinking to make their snare the greater, and being minded to drive Him to a necessity of contradicting the law, they say not, why did You enact this or that? But as though nothing had been said, they ask, “Is it lawful?” expecting that He had forgotten having said it; and being ready if on the one hand He said, “It is lawful to put away,” to bring against Him the things He Himself had spoken, and to say, How then did You affirm the contrary? But if the same things now again as before, to bring against Him the words of Moses.
What then said He? He said not, do you tempt me, you hypocrites? although afterwards He says this, but here He speaks not thus. Why can this be? In order that together with His power He might show forth His gentleness also. For He does neither always keep silence, lest they should suppose they are hidden; nor does He always reprove, in order that He may instruct us to bear all things with gentleness.
How then does He answer them? “Have ye not read, that He which made them at the beginning, made them male and female, and said, For this cause shall a man leave his father and his mother, and shall cleave to his wife; and they two shall be one flesh? So that they are no more two but one flesh. What therefore God has joined together, let not man put asunder.”
See a teacher's wisdom. I mean, that being asked, Is it lawful? He did not at once say, It is not lawful, lest they should be disturbed and put in disorder, but before the decision by His argument He rendered this manifest, showing that it is itself too the commandment of His Father, and that not in opposition to Moses did He enjoin these things, but in full agreement with him.
But mark Him arguing strongly not from the creation only, but also from His command. For He said not, that He made one man and one woman only, but that He also gave this command that the one man should be joined to the one woman. But if it had been His will that he should put this one away, and bring in another, when He had made one man, He would have formed many women.
But now both by the manner of the creation, and by the manner of lawgiving, He showed that one man must dwell with one woman continually, and never break off from her.
And see how He says, “He which made them at the beginning, made them male and female,” that is, from one root they sprung, and into one body came they together, “for the two shall be one flesh.”
After this, to make it a fearful thing to find fault with this lawgiving, and to confirm the law, He said not, “Sever not therefore, nor put asunder,” but, “What God has joined together, let not man put asunder.”
But if you put forward Moses, I tell you of Moses' Lord, and together with this, I rely upon the time also. For God at the beginning made them male and female; and this law is older (though it seem to have been now introduced by me), and with much earnestness established. For not merely did He bring the woman to the man, but also commanded to leave father and mother. And neither did He make it a law for him merely to come to the woman, but also “to cleave to her,” by the form of the language intimating that they might not be severed. And not even with this was He satisfied, but sought also for another greater union, “for the two,” He says, “shall be one flesh.”
Then after He had recited the ancient law, which was brought in both by deeds and by words, and shown it to be worthy of respect because of the giver, with authority after that He Himself too interprets and gives the law, saying, “So that they are no more two, but one flesh.” Like then as to sever flesh is a horrible thing, so also to divorce a wife is unlawful. And He stayed not at this, but brought in God also by saying, “What therefore God has joined together, let not man put asunder,” showing that the act was both against nature, and against law; against nature, because one flesh is dissevered; against law, because that when God has joined and commanded it not to be divided, you conspire to do this.
