2 Kings 18:7

Rebelled — He shook off that yoke of subjection, to which his father had wickedly submitted, and reassumed that full and independent sovereignty which God had settled in the house of David. And Hezekiah's case differs much from that of Zedekiah, who is blamed for rebellion against the king of Babylon, both because he had engaged himself by a solemn oath and covenant, which we do not read of Ahaz; and because he broke the covenant which he himself had made; and because God had actually given the dominion of his own land and people to the king of Babylon, and commanded both Zedekiah and his people to submit to him. And whereas Hezekiah is here said to rebel; that word implies, only a defection from that subjection which had been performed to another; which sometimes may be justly done, and therefore that word doth not necessarily prove this to be a sin. And that it was not a sin in him, seems certain, because God owned and assisted him therein; and did not at all reprove him for it, in that message which he sent to him by Isaiah, nor afterwards, though he did particularly reprove him, for his vain — glory, and ostentation, 2 Chronicles 32:25.
