Forty-five Days between Daniel 12:11-12
[Commentary on John 7:27]
[When Christ cometh, no man knoweth whence he is.] How doth this agree with verse 42, and with Matthew 2:5, 6? They doubted not, indeed, but he should give the first manifestation of himself from Bethlehem; but then they supposed he would be hid again; and after some space of time make a new appearance, from what place no one could tell.
Jewish authors tell you, that Christ, before their times, had indeed been born in Bethlehem, but immediately snatched away they knew not whither, and so hid that he could not be found. We related the whole story before in our notes at Matthew 2:1.
Their conceptions in this thing we have explained to us in Midras Schir: "'My beloved is like a roe or a young hart,' Canticles 2:9. A roe appears and is hid, appears and is hid again. So our first redeemer [Moses] appeared and was hid, and at length appeared again. So our latter Redeemer [Messiah] shall be revealed to them, and shall be hid again from them; and how long shall he be hid from them?" &c. A little after; "In the end of forty-five days he shall be revealed again, and cause manna to descend amongst them."
They conceive a twofold manifestation of the Messiah; the first, in Bethlehem; but will straightway disappear and lie hid. At length he will shew himself; but from what place and at what time that will be, no one knew. In his first appearance in Bethlehem, he should do nothing that was memorable; in his second was the hope and expectation of the nation. The Jews therefore who tell our Saviour here, that "when Christ cometh, no man knoweth whence he is," whether they knew him to have been born at Bethlehem or no, yet by his wonderful works they conceive this to have been the second manifestation of himself: and therefore only doubt whether he should be the Messiah or no, because they knew the place [Nazareth] from whence he came; having been taught by tradition, that Messiah should come the second time from a place perfectly unknown to all men.
