I. Note the trial of faith. Rabshakeh had derided the obstinate confidence in Jehovah, which kept these starving men on the walls grimly silent in spite of his coaxing. The letter of Sennacherib harps on the same string. It is written in a tone of assumed friendly remonstrance, and lays out with speciousness the apparent grounds for calling trust in Jehovah absurdity. There are no threats in it. It is all an appeal to common sense and political prudence. It marshals undeniable facts. Experience has shown the irresistible power of Assyria. There have been plenty of other little nations which have trusted in their local deities, and what has become of them? Barbarous names are flourished in Hezekiah's face, and their wasted dominions are pointed to as warnings against his committing a parallel folly. There is nothing in the letter which might not have been said by a friend, and nothing which was not said by the Jews who had lost their faith in their God. It was but the putting into plain words of what 'common-sense' and faint faith had often whispered to Hezekiah. The very absence of temper or demand in the letter gives it an aspect of that 'sweet reasonableness' so dear to sense-bound souls. _Mutatis mutandis_, the letter may stand for a specimen of the arguments which worldly prudence brings to shake faith, in all ages. We, too, are assailed by much that sounds most forcible from the point of view of mere earthly calculation. Sennacherib does not lie in boasting of his victories. He and his shoals of soldiers are very real and potent. It does seem madness for one little kingdom to stand out, and all the more so because its king is cooped up in his city, as the cuneiform inscription proudly tells, 'like a bird in a cage,' and all the rest of his land is in the conqueror's grip. They who look only at the things seen cannot but think the men of faith mad. They who look at the things unseen cannot but know that the men of sense are fools. The latter elaborately prove that the former are impotent, but they have left out one factor in their calculations, and that is God. One man and God at his back are stronger than Sennacherib and all his mercenaries.
