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 front the broad and burnished surface of the Almighty buckler, all the darts that any foe can launch against as. '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.
II. We note the reality meant by these pictures.
They mean the absolute promise from God of protection for His people from _every_ evil. We are not to cut it down, not to say that it applies absolutely in regard to the spiritual world, but that it does not apply in regard to temporal things. Yes, it does entirely, only you have to rise to the height of God's conception of what is good and what is evil in regard to outward things, before you understand how completely, and without qualification or deduction, this promise is fulfilled to every man that puts his trust in Him. Of course, I do not need to remind you, for your own lives will do so sufficiently, that this hovering protector, this strong Shield, this Destroying Angel that passes by our houses if the blood is on the threshold, does not guarantee us any exemption from the common 'ills that flesh is heir to.' We all know that well enough. But what does it guarantee? That all the poison shall be wiped off the arrow, that all the evil shall be taken out of the evil, that it will change its character, that if we observe the conditions, the sharpest sorrow will come to us with this written on it by the Father's hand, 'With My love to My child'; that pain will be discipline, and discipline will be blessed. Ah! dear friends! I am sure there are many of us that can set to our seals that God is true in this matter, and that we have found that His rod does blossom, and that our sorest sorrows have been our greatest mercies, drawing us nearer to Him; 'Defending He will deliver, and passing over He will preserve.'
