“(de Con. Evan. 2. 51) Now in Matthew we read that He entered into the parts of Magdala1. But we cannot doubt that it is the same place under another name; for several manuscripts even of St. Mark have only Magdala. It goes on, And the Pharisees came forth, and began to question with him, seeking of him a sign from heaven, tempting him.”

“(ubi sup.) Let no one, however, be perplexed that the answer which Mark says was given to them, when they sought a sign from heaven, is not the same as that which Matthew relates, namely, that concerning Jonah. He says that the Lord’s answer was, that no sign should be given to it; by which we must understand such an one as they asked for, that is, one from heaven; but he has omitted to say, what Matthew has related.”

“(in Marc. 2, 33) The Pharisees, then, seek a sign from heaven, that He, Who had for the second time fed many thousands of men with a few loaves of bread, should now, after the example of Moses, refresh the whole nation in the last time with manna sent down from heaven, and dispersed amongst them all.”

“Now the reason why the Lord did not listen to them was, that the time of signs from heaven had not arrived, that is, the time of the second Advent, when the powers of the heaven shall be shaken, and the moon shall not give her light. But in the time of the first Advent, all things are full of mercy, and such things do not take place.”

“And the Pharisees came forth,.... Out of their houses; who dwelt in the coasts of Magdala, and parts of Dalmanutha, and came to Jesus, hearing of his being arrived in their neighbourhood: and began to question with him; or to dispute with him, it being their manner to carry on disputations by questions and answers. The Persic version has the question they put, and about which they disputed, "if thou art the Christ"; in proof of which they required a sign: seeking of him a sign from heaven, tempting him; See Gill on Mat 16:1.”

1774–1849
“Jesus Christ did not consent to the petition they made him, because there will be another time for signs and wonders, viz. his second coming, when the powers of heaven shall be moved, and the moon refuse her light. This his first coming is not to terrify man, but to instruct and store his mind with lessons of humility, and every other virtue. (Theophylactus)”
