The answer is: A prophet of Judah

2 Kings 23:17-18 - The same prophet who made the prophecy hundreds of years earlier

The story of Josiah discovering an undisturbed grave at Bethel is like a treasure chest of prophetic significance! This prophet of Judah, who heeded warning centuries before, echoes themes of holiness and divine intent in ancient Israel. What makes this moment so rich is its reminder of the power of prophecy—the same words that foretold Jerusalem's eventual salvation against idolatry and corruption are now being acknowledged by a king swept up in purifying winds.

Josiah's vibes of reform resounded not just through physical changes in places of worship but also through spiritual awakenings in the land. A descendant of David, this young king wasn’t just seeking to reinvent Judean practices but rather restore them back to their glorious origins. Imagine that—walking through the dusty roads of Bethel, you stumble upon a osteoleolic artifact from the past still holding divine meaning!

As a side interesting note, Bethel itself wasn’t just any old town. It was a key hub in God's narrative, associated with dreams (like Jacob's ladder) and sacred encounters. And it's profound to consider that this simple tomb served as a bridge between ancient words and present realities. It's a gentle reminder to honor those who laid out the spiritual framework through their implied sacrifices, who guide future generations long after they’ve laid down their lives. So, in a way, the prophet’s story goes on; perhaps this triggered even more memories or awakenings for Josiah than the reforms themselves!
