_See I have this day set thee over the nations and over the kingdoms, to root out and to pull down, and to destroy and to overturn; to rebuild and to replant._ Such, following the Hebrew punctuation, are the terms of the prophet's commission; and they are well worth consideration, as they set forth with all the force of prophetic idiom his own conception of the nature of that commission. First, there is the implied assertion of his own official dignity: the prophet is made a _paqîd_ (Gen. xli. 34, "officers" set by Pharaoh over Egypt; 2 Kings xxv. 19 a military prefect) a prefect or superintendent of the nations of the world. It is the Hebrew term corresponding to the ἐπίσκοπος of the New Testament and the Christian Church (Judg. ix. 28; Neh. xi. 9). And secondly, his powers are of the widest scope; he is invested with authority over the destinies of all peoples. If it be asked in what sense it could be truly said that the ruin and renascence of nations was subject to the supervision of the prophets, the answer is obvious. The word they were authorised to declare was the word of God. But God's word is not something whose efficacy is exhausted in the human utterance of it. God's word is an irreversible command, fulfilling itself with all the necessity of a law of nature. The thought is well expressed by a later prophet: "For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and spring; and yieldeth seed to the sower and bread to the eater: so shall My word become, that goeth forth out of My mouth; it shall not return to Me empty (ריקם), but shall surely do that which I have willed, and shall carry through that for which I sent it" (or "shall prosper him whom I have sent," Isa. lv. 10, 11). All that happens is merely the selfaccomplishment of this Divine word, which is only the human aspect of the Divine will. If, therefore, the absolute dependence of the prophets upon God for their knowledge of this word be left out of account, they appear as causes, when they are in truth but instruments, as agents when they are only mouthpieces. And so Ezekiel writes, "when I came to destroy the city" (Ezek. xliii. 3), meaning when I announced the Divine decree of its destruction. The truth upon which this peculiar mode of statement rests--the truth that the will of God must be and always is done in the world that God has made and is making--is a rock upon which the faith of His messengers may always repose. What strength, what staying power may the Christian preacher find in dwelling upon this almost visible fact of the self-fulfilling will and word of God, though all around him he hear that will questioned, and that word disowned and denied! He knows--it is his supreme comfort to know--that, while his own efforts may be thwarted, that will is invincible; that though _he_ may fail in the conflict, that word will go on conquering and to conquer, until it
