1 Kings 13:2

A child shall be born ... Josiah by name - Divine predictions so seldom descend to such particularity as this, that doubts are entertained, even by orthodox theologians, with respect to the actual mention of Josiah’s name by a prophet living in the time of Jeroboam. Only one other instance that can be considered parallel occurs in the whole of Scripture - the mention of Cyrus by Isaiah. Of course no one who believes in the divine foreknowledge can doubt that God could, if He chose, cause events to be foretold minutely by his prophets; but certainly the general law of his Providence is, that He does not do so. If this law is to be at any time broken through, it will not be capriciously. Here it certainly does not appear what great effect was to be produced by the mention of Josiah’s name so long before his birth; and hence, a doubt arises whether we have in our present copies the true original text. The sense is complete without the words “Josiah by name;” and these words, if originally a marginal note, may easily have crept into the text by the mistake of a copyist. It is remarkable that, where this narrative is again referred to in Kings (marginal reference), there is no allusion to the fact that the man of God had prophesied of Josiah “by name.”
