The immediate occasion of this very remarkable promise is, of course, the peril in which Jerusalem was placed by Sennacherib's invasion; and the fulfilment of the promise was the destruction of his army before its gates. But the promise here, like all God's promises, is eternal in substance, and applies to a community only because it applies to each member of that community. Jerusalem was saved, and that meant that every house in Jerusalem was saved, and every man in it the separate object of the divine protection So that all the histories of Scripture, and all the histories of men in the world, are but transitory illustrations of perennial principles, and every atom of the consolation and triumph of this verse comes to each of us, as truly as it did to the men that with tremulous heart began to take cheer, as they listened to Isaiah. There is a wonderful saying in one of the other prophets which carries that lesson, where, bringing down the story of Jacob's struggle with the angel of Peniel to the encouragement of the existing generation, he says,' He spake to _us_.' They were hundreds of years after the patriarch, and yet had fallen heirs to all that God had ever said to him So, from that point of view, I am not spiritualising, or forcing the meaning of these words, when I bring them direct into the lives of each one of ourselves. I. And, first, I would note the very striking and beautiful pictures that are given in these verses. There are three of them, on each of which I must touch briefly. 'As birds flying, so will the Lord of hosts defend Jerusalem.' The form of the words in the original shows that it is the mother-bird that is thought about. And the picture rises at once of her fluttering over the nest, where the callow chickens are, unable to fly and to help themselves. It is a kind of echo of the grand metaphor in the song that is attributed to Moses, which speaks of the eagle fluttering over her nest, and taking care of her young. Jerusalem was as a nest on which, for long centuries, that infinite divine love had brooded. It was but a poor brood that had been hatched out, but yet 'as birds flying' He had watched over the city. Can you not almost see the mother-bird, made bold by maternal love, swooping down upon the intruder that sought to rob the nest, and spreading her broad pinion over the callow fledglings that lie below? That is what God does with us. As I said, it is a poor brood that is hatched out. That does not matter; still the Love bends down and helps. Nobody but a prophet could have ventured on such a metaphor as that, and nobody but Jesus Christ would have ventured to mend it and say, 'As a hen gathereth her chickens under her wings,' when there are hawks in the sky. So He, in all the past ages, was the One that 'as birds flying ... defended' His people, and would have gathered them under His wings, only they would not.
