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.
Now, beautiful as this metaphor is, as it stands, it seems to me, like some brilliant piece of colouring, to derive additional beauty from its connection with the background upon which it stands out. For just a verse before the prophet has given another emblem of what God is and does, and if you will carry with you all those thoughts of tenderness and maternal care and solicitude, and then connect them with that verse, I think the thought of His tenderness will start up into new beauty. For hero is what precedes the text: Like as a lion, and the young lion roaring on his prey when a multitude of shepherds is called forth against him, he will not be afraid of their voice, nor bow himself for the noise of them. So shall the Lord of hosts come down to fight for Mount Zion.' Look at these two pictures side by side, on the one hand the lion, with his paw on his prey, and the angry growl that answers when the shepherds vainly try to drag it away from him. That is God. Ay! but that is only an aspect of God. As birds flying, so the Lord will defend Jerusalem.' We have to take that into account too. This generation is very fond of talking about God's love; does it believe in God's wrath? It is very fond of speaking about the gentleness of Jesus; has it pondered that tremendous phrase, the wrath of the Lamb'? The lion that growls, and the mother-bird that hovers--God is like them both. That is the first picture that is here.
The second one is not so obvious to English readers, but it is equally striking, though I do not mean to dwell upon it. The word that is translated in our text twice, defend' and defending'--So will the Lord of hosts defend Jerusalem, and defending will deliver'--means, literally, shielding.' Thus we have the same general idea as that in the previous metaphor of the mother-bird hovering above the nest: God is like a shield held over us, and so flinging off from the broad and burnished surface of the Almighty buckler, all the darts that any foe can launch against us. Our God is a Sun and Shield.' I need not enlarge on this familiar metaphor.
But the third picture I wish to point to in more detail: Passing over, He will deliver.' Now, the word that is there rendered passing over,' is almost a technical word in the Old Testament, because it is that employed in reference to the Passover. And so you see the swiftness of genius with which the prophet changes his whole scene. We had the nest and the mother-bird, we had the battlefield and the shield; now we are swept away back to that night when the Destroying Angel stalked through the land, and passed over' the doors on which the blood had been sprinkled. And thus this God, who in one aspect may be likened to the mother-bird hovering with her little breast full of tenderness, and made brave by maternal love conquering natural timidity, and in another aspect may be likened to the broad shield behind which a man stands safe, may also be likened to that Destroying Angel that went through Egypt, and smote wherever there were not the tokens of the blood on the lintels, and passed over' wherever there were. Of course, the original fulfilment of this third picture is the historical case of the army of Sennacherib; outside the walls, widespread desolation; inside the walls, an untroubled night of peace. That night in Egypt is paralleled, in the old Jewish hymn that is still sung at the Passover, with the other night when Sennacherib's men were slain; and the parallel is based on our text. So, then, here is another illustration of what I started with saying, that the past events of Scripture are transient expressions of perennial principles and tendencies. For the Passover night was not to be to the contemporaries of the prophet an event receding ever further into the dim distance, but it was a present event, and to be reproduced in that catastrophe when in the morning when they arose, they were all dead corpses.' And the event is being repeated to-day, and will be for each of us, if we will.
So, then, there are these three pictures, the Nest and the Mother-bird, the Battlefield and the Shield, Egypt and the Destroying Angel.
