The public danger, which stimulated the reflexion and lent force to the invective of the lesser prophet, intensified the impression produced by the earlier preaching of Jeremiah. The tide of invasion, indeed, rolled past Judea, without working much permanent harm to the little kingdom, with whose destinies were involved the highest interests of mankind at large. But this respite from destruction would be understood by the prophet's hearers as proof of the relentings of Iahvah towards His penitent people; and may, for the time at least, have confirmed the impression wrought upon the popular mind by Jeremiah's passionate censures and entreaties. The time was otherwise favourable; for the year of his call was the year immediately subsequent to that in which the young king Josiah "began to purify Judah and Jerusalem from the high places and the Asherim, and the carven images and the molten images," which he did in the twelfth year of his reign, _i.e._ in the twentieth year of his age, according to the testimony of the Chronicler (2 Chron. xxxiv. 3), which there is no good reason for disallowing. Jeremiah was probably about the same age as the king, as he calls himself a mere youth (na`ar). After the Scythians had retired--if we are right in fixing their invasion so early in the reign--the official reformation of public worship was taken up again, and completed by the eighteenth year of Josiah, when the prophet might be about twenty-five. The finding of what is called "the book of the Law," and "the book of the Covenant,"[12] by Hilkiah the high priest, while the temple was being restored by the king's order, is represented by the histories as having determined the further course of the royal reforms. What this book of the Law was, it is not necessary now to discuss. It is clear from the language of the book of Kings, and from the references of Jeremiah, that the substance of it, at any rate, closely corresponded with portions of Deuteronomy. It appears from his own words (chap. xi. 1-8) that at first, at all events, Jeremiah was an earnest preacher of the positive precepts of this book of the Covenant. It is true that his name does not occur in the narrative of Josiah's reformation, as related in Kings. There the king and his counsellors inquire of Iahvah through the prophetess Huldah (2 Kings xxii. 14). Supposing the account to be both complete and correct, this only shows that five years after his call, Jeremiah was still unknown or little considered at court. But he was doubtless included among the "prophets," who, with "the king and all the men of Judah and all the inhabitants of Jerusalem," "and the priests ... and all the people, both small and great," after the words of the newfound book of the Covenant had been read in their ears, bound themselves by a solemn league and covenant, "to walk after Iahweh, and to keep His commandments, and His laws, and His statutes, with all the heart, and with all the soul" (2 Kings xxiii. 3).
