John Gill Bible Commentary

Then he said unto them,.... That is, Jesus said unto them, as the Syriac and Persic versions read: O fools; not in a natural sense, as if they were destitute of the common understanding of men; nor in a moral sense, as wicked men, and as they themselves had been in their unregenerate estate; nor in a way of anger and contempt, and with a design to provoke; wherefore Christ did not act contrary to his own rule, in Mat 5:22 but because they were so void of understanding in the Scriptures, and were so very ignorant of them, and were so blind as to the knowledge of them; particularly those which concerned the sufferings and resurrection of the Messiah, being influenced by the popular prejudices of education: he therefore expresses himself with much warmth, concern, and surprise, that he should have been so long with them, and they so long under his doctrine and ministry; besides the advantages of having the Scriptures, and being conversant with them from their youth; and which they daily read, and had heard expounded, and yet were so very senseless and stupid: and slow of heart to believe all that the prophets have spoken; that is, upon these points, concerning the sufferings of Christ, and his resurrection from the dead; and indeed, they were very slow of heart to believe, not only what the women reported from the angels, but even those of their brethren, who had seen him after he was risen; for which Christ upbraids them, Mar 16:14. Yea, one of them declared after all, that he would not believe, unless he saw the print of the nails in his hands and feet, and put his hand into it, and thrust it into his side; wherefore Christ had good reason to treat them in this sharp manner, and charge them with folly and incredulity; the Jews ought not to object to the word "fools", as unbecoming Christ, since they frequently represent God as making use of it; as for instance, it is said, (x). "the holy blessed God said to them, "O ye fools" that are in the world, whatsoever ye do, ye do for your own necessities. ---And a little after, "O ye fools" that are in the world, he that labours on the evening of the sabbath, shall eat on the sabbath day.'' (x) T. Bab. Avoda Zara, fol. 2. 2. & 3. 1.
