Ahaz observed a dignified silence after those words of the Prophet; but his whole manner shews the Prophet that they have not made any impression upon him. If David's spirit had rested on Ahaz, he would surely, if he had wavered at all, have, on the word of the Prophet, thrown himself into the arras of his God. But in order that the depth of his apostacy, the greatness of his guilt, and the justice of the divine judgments may become manifest, God shows him even a deeper condescension. The Prophet offers to prove the truth of his announcement by any miraculous work which the king himself should determine, and from which he might, at the same time, see God's omnipotence, and the Divine mission of the Prophet. As Ahaz refused the offered sign, the word 2 Tim. ii. 12, 13: εἰ ἀρνούμεθα, κἀκεῖνος ἀρνήσεται ἡμᾶς• εἰ ἀπιστοῦμεν, ἐκεῖνος πιστὸς μένει·--ἀρνήσασθαι γὰρ ἑαυτὸν οὐ δύναται came into application. According to Deut. vii. 9 ff. the truth and faithfulness of God must now manifest itself in the [Pg 39] infliction of severe visitations upon the house of David.--The character of a _sign_ is, in general, borne by everything which serves for certifying facts which belong to the territory of faith, and not to that of sight. 1. In some instances, the sign consists in a mere naked word; thus in Exod. iii. 12: "And this shall be the sign unto thee that I have sent thee: When thou hast brought forth the people out of Egypt, ye shall serve God upon this mountain." Moses' doubts of the truth of his Divine mission originated in the consciousness of his own unworthiness, and in the condition of those to whom he was sent. From these doubts he was delivered by the announcement that, at the place where he had been called, he, at the head of the delivered people, should serve his God. This was to him a _sign_ that God was in earnest in calling him. 2. In other instances the assurance given by the sign consists in its perceptibility and corporeality; so that the word assumes, as it were, flesh and blood. A case of this kind it is, _e.g._, when, in chap. viii. 18, Isaiah calls his two sons, to whom, at the command of God, he had given symbolical names, expressive of the future salvation of the covenant-people, "Signs and wonders in Israel;" farther, chap. xx. 3, where the Prophet walks naked and barefoot for a sign of the calamity impending over Egypt and Ethiopia in three years. 3. In another class of signs, a fact is announced which is, in itself, natural, but not to be foreseen by any human combination, the coming to pass of which, in the immediate future, furnishes the proof that, at a distant future, that will be fulfilled which was foretold as impending. The wonderful element, and the demonstrative power do not, in such a case, lie in the matter of the sign, but in the telling of it beforehand. It is in this sense that, in 1 Sam. x., Samuel gives several _signs_ to Saul, that God had destined him to be king, _e.g._,
