2 Kings 18:7 - Matthew Poole's English Annotations on the Holy Bible

He shook off that yoke of subjection and tribute to which his father had wickedly submitted, 2 Kings 16:7, and reassumed that full and independent sovereignty which God had settled in the house of David, which Ahaz could not alienate further than for his own time. 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 to him 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 professed and performed to another: which sometimes may be justly done, and sometimes may not; and therefore that word doth not necessarily prove this action to be a sin. And these words, he rebelled, & c., are explained by the next following words, and he served him not. And that it was not a sin in him seems most probable because God did own and assist him therein; and did not at all reprove him for it in that message which he sent to him by Isaiah about this matter, 2 Kings 19:20, &c., nor afterwards, though he did particularly reprove him for that which might seem a less fault, for his vain-glory and ostentation, 2 Chronicles 32:25,26. For what he saith, I have offended, See Poole on "2 Kings 18:14".
