Catena Aurea · Matthäusevangelium 21
And he left them, and went out of the city into Bethany; and he lodged there. Now in the morning as he returned into the city, he hungered. And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on thee henceforward for ever. And presently the fig tree withered away. And when the disciples saw it, they marvelled, saying, How soon is the fig tree withered away! Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done. And all things, whatsoever ye shall ask in prayer believing, ye shall receive.
(de Cons. Ev. ii. 68.) It must be considered that Mark relates the wonder of the disciples at the withering of the tree, and the answer of the Lord concerning faith, to have been not on the day following the cursing of the tree, but on the third day after; and that on the second day Mark relates the casting of the merchants out of the Temple, which he had omitted on the first day. On the second day then he says that He went forth out of the city in the evening, and that as they passed by in the morning, the disciples then saw that the fig tree was withered. But Matthew speaks as though all this had been done on the day following. This must be so taken as that when Matthew, having related that the fig tree was dried up, adds immediately, omitting all the events of the second day, And when the disciples saw if, they marvelled, he yet meant that it was on another day that they marvelled. For the tree must be supposed to have withered at the time it was cursed, not at the time they saw it. For they did not see it withering, but when it was withered, and by that they understood that it had withered immediately upon the Lord’s words.
