Jeremiah 1:2
To whom the word of the LORD came in the days of Josiah the son of Amon king of Judah, in the thirteenth year of his reign.
To whom the word of the Lord came in the days of Josiah,.... This was the beginning of the prophecy of Jeremiah, so that he prophesied long after Isaiah, Hosea, Amos, and Micah; for this king was
the son of Amon king of Judah, which Amon was the son of Manasseh; the Septuagint and Arabic versions wrongly call him Amos; and Jeremiah began to prophesy
in the thirteenth year of his reign: in the twenty first of Josiah's age, for he began to reign when he was eight years old, and he reigned eighteen years after, for he reigned in all thirty one years; and it was five years after this that the book of the law was found by Hilkiah the high priest, 2 Kings 22:3.
