Matthew 21:12-13.
“And Jesus went into the temple, and cast out all them that sold and bought in the temple, and overthrew the tables of the money-changers and the seats of them that sold doves, and says unto them, It is written, my house shall be called a house of prayer; but you have made it a den of thieves.”
This John likewise says, but he in the beginning of his Gospel, this at the end. Whence it is probable this was done twice, and at different seasons.
And it is evident both from the times, and from their reply. For there He came at the very passover, but here much before. And there the Jews say, “What sign do you show us?” but here they hold their peace, although reproved, because He was now marvelled at among all men.
And this is a heavier charge against the Jews, that when He had done this not once only, but a second time, they continued in their trafficking, and said that He was an adversary of God, when they ought even from hence to have learned His honor for His Father and His own might. For indeed He also wrought miracles, and they saw His words agreeing with His works.
But not even so were they persuaded, but “were sore displeased,” and this while they heard the prophet crying aloud, and the children in a manner beyond their age proclaiming Him. Wherefore also He Himself sets up Isaiah against them as an accuser, saying, “My house shall be called a house of prayer.”
But not in this way only does He show His authority, but also by His healing various infirmities. “For the blind and the lame came unto Him, and He healed them,” and His power and authority He indicates.
But they not even so would be persuaded, but together with the rest of the miracles hearing even the children proclaiming, were ready to choke, and say, “Do you not hear what these say?” And yet it was Christ's part to have said this to them, “Hear ye not what these say?” for the children were singing to Him as to God.
What then says He? Since they were speaking against things manifest, He applies His correction more in the way of reproof, saying, “Have ye never read, Out of the mouths of babes and sucklings You have perfected praise?” And well did He say, “Out of the mouth.” For what was said was not of their understanding, but of His power giving articulation to their tongue yet immature.
And this was also a type of the Gentiles lisping, and sounding forth at once great things with understanding and faith.
And for the apostles also there was from hence no small consolation. For that they might not be perplexed, how being unlearned they should be able to publish the gospel, the children anticipate them, and remove all their anxiety, teaching them, that He would grant them utterance, who made even these to sing praises.
And not so only, but the miracle showed that He is Creator even of nature. The children then, although of age immature, uttered things that had a clear meaning, and were in accordance with those above, but the men things teeming with frenzy and madness. For such is the nature of wickedness.
Forasmuch then as there were many things to provoke them, from the multitude, from the casting out of the sellers, from the miracles, from the children, He again leaves them, giving room to the swelling passion, and not willing to begin His teaching, lest boiling with envy they should be the more displeased at His sayings.
“Now in the morning as He returned into the city, He was an hungered.” How is He an hungered in the morning? When He permits the flesh, then it shows its feeling. “And when He saw a fig tree in the way, He came to it, and found nothing thereon, but leaves only.” Another evangelist says, “The time of figs was not yet;” but if it was not time, how does the other evangelist say, “He came, if haply He might find fruit thereon.” Whence it is manifest that this belongs to the suspicion of His disciples, who were yet in a somewhat imperfect state. For indeed the evangelists in many places record the suspicions of the disciples.
Like as this then was their suspicion, so also was it too to suppose it was cursed for this cause, because of having no fruit. Wherefore then was it cursed? For the disciples' sakes, that they might have confidence. For because everywhere He conferred benefits, but punished no man; and it was needful that He should afford them a demonstrative proof of His power to take vengeance also, that both the disciples might learn, and the Jews, that being able to blast them that crucify Him, of His own will He submits, and does not blast them; and it was not His will to show forth this upon men; upon the plant did He furnish the proof of His might in taking vengeance. But when unto places, or unto plants, or unto brutes, any such thing as this is done, be not curious, neither say, how was the fig-tree justly dried up, if it was not the time of figs; for this it is the utmost trifling to say; but behold the miracle, and admire and glorify the worker thereof.
Since in the case also of the swine that were drowned, many have said this, working out the argument of justice; but neither there should one give heed, for these again are brutes, even as that was a plant without life.
Wherefore then was the act invested with such an appearance, and with this plea for a curse? As I said, this was the disciple's suspicion.
But if it was not yet time, vainly do some say the law is here meant. For the fruit of this was faith, and then was the time of this fruit, and it had indeed borne it; “For already are the fields white to harvest,” says He; and, “I sent you to reap that whereon ye bestowed no labor.”
2. Not any therefore of these things does He here intimate, but it is what I said, He displays His power to punish, and this is shown by saying, “The time was not yet,” making it clear that of this special purpose He went, and not for hunger, but for His disciples' sake, who indeed marvelled exceedingly, although many miracles had been done greater; but, as I said, this was strange, for now first He showed forth His power to take vengeance. Wherefore not in any other, but in the moistest of all planted things did He work the miracle, so that hence also the miracle appeared greater.
And that you might learn, that for their sakes this was done, that He might train them to feel confidence, hear what He says afterwards. But what says He? “You also shall do greater things, if you are willing to believe and to be confident in prayer.” Do you see that all is done for their sake, so that they might not be afraid and tremble at plots against them? Wherefore He says this a second time also, to make them cleave to prayer and faith. “For not this only shall you do, but also shall remove mountains; and many more things shall you do, being confident in faith and prayer.”
But the boastful and arrogant Jews, wishing to interrupt His teaching, came unto Him, and asked, “By what authority doest thou these things?” For since they could not object against the miracles, they bring forward against Him the correction of the traffickers in the temple. And this in John also they appear to ask, although not in these words, but with the same intent. For there too they say, “What sign do you show unto us? Seeing that you do these things.” But there He answers them, saying, “Destroy this temple, and I in three days will raise it up,” whereas here He drives them into a difficulty. Whence it is manifest, that then indeed was the beginning and prelude of the miracles, but here the end.
But what they say is this: Have you received the teacher's chair? Have you been ordained a priest, that you displayed such authority? It is said. And yet He had done nothing implying arrogance, but had been careful for the good order of the temple, yet nevertheless having nothing to say, they object against this. And indeed when He cast them out, they did not dare to say anything, because of the miracles, but when He showed Himself, then they find fault with Him.
