“Therefore thus says the Lord concerning the king of Assyria: He shall not come into this city or shoot an arrow there, or come before it with a shield or cast up a siege mound against it.” -2 Kings 19:32
Neither did Sennacherib molest the city. He had boasted loudly, but he could not carry out his threats. The Lord is able to stop the enemies of His people in the very act. When the lion has the lamb between his jaws, the great Shepherd of the sheep can rob him of his prey. Our extremity only provides an opportunity for a grander display of divine power and wisdom.
In the case before us, the terrible foe did not put in an appearance before the city which he thirsted to destroy. No annoying arrow could he shoot over the walls, and no besieging engines could- he put to work to batter down the castles, and no banks could he cast up to shut in the inhabitants. Perhaps in our case also the Lord will prevent our adversaries from doing us the least harm. Certainly He can alter their intentions or render their designs so abortive that they will gladly forego them. Let us trust in the Lord and keep His way, and He will take care of us. Yea, He will fill us with wondering praise as we see the perfection of His deliverance.
Let us not fear the enemy till he actually comes, and then let us trust in the Lord.
