John Wesley on 2 Kings 18:5

Trusted - Without calling in foreign succours to establish or help him; which his father Ahaz did; and before him Asa. Before him - Of the kings of Judah only; for David and Solomon were kings of all Israel. The like is said of Josiah, chap.23:25. Each of them, excelled the other in several respects. Hezekiah in this, that he fell upon this work in the beginning of his reign, which Josiah did not, and with no less resolution, undertaking to do that which none of his predecessors durst do, even to remove the high places, wherein Josiah did only follow his example.
