So Hilkiah the priest, and Ahikam, and Achbor, and Shaphan, and Asaiah went to Huldah the prophetess, the wife of Shallum the son of Tikvah, son of Harhas, keeper of the wardrobe (now she lived in Jerusalem in the Second Quarter), and they talked with her. And she said to them, “Thus says the Lord, the God of Israel: ‘Tell the man who sent you to me, Thus says the Lord, Behold, I will bring disaster upon this place and upon its inhabitants, all the words of the book that the king of Judah has read. Because they have forsaken me and have made offerings to other gods, that they might provoke me to anger with all the work of their hands, therefore my wrath will be kindled against this place, and it will not be quenched. But to the king of Judah, who sent you to inquire of the Lord, thus shall you say to him, Thus says the Lord, the God of Israel: Regarding the words that you have heard, because your heart was penitent, and you humbled yourself before the Lord, when you heard how I spoke against this place and against its inhabitants, that they should become a desolation and a curse, and you have torn your clothes and wept before me, I also have heard you, declares the Lord. Therefore, behold, I will gather you to your fathers, and you shall be gathered to your grave in peace, and your eyes shall not see all the disaster that I will bring upon this place.’” And they brought back word to the king. 2 Kings 22:14-20.
King Josiah went outside the priestly authorities to get counsel for a reason: they were part of the problem. They did not oppose the last evil king and his Baal worship. They only had the books of the law to consult because the temple cleanup crew found them.
Hulduh was an outsider, known to have God’s ear, and He had hers. During the worst of times, there is always someone who is faithful, when everyone else is selling out. The authorities can’t root them all out, just as there was always that annoying prophet the wicked king cannot bear to hear, and can’t kill him either.
If you are often sad because of the lukewarmness of the church, the corruption of it’s leadership, and the absence of the word of the Lord, you might be a prophet.
