John Gill's Bible Commentary Ver. 7. And the Lord was with him , etc.] The Word of the Lord was for his help, as the Targum: and he prospered whithersoever he went forth ; that is, to war: and he rebelled against the king of Assyria : which is explained in the next clause: and served him not ; he refused to be his servant, as his father Ahaz had been, ( 2 Kings 16:7), to which he was not obliged by any agreement of his; and, if it was in his power, might lawfully shake off his yoke, which is all that is meant by rebelling against him; he refused to be tributary to him.
Matthew Henry Commentary
Verses 1-8 - Hezekiah was a true son of David. Some others did that which was right but not like David. Let us not suppose that when times and men are bad they must needs grow worse and worse; that does not follow: after man bad kings, God raised one up like David himself. The brazen serpent ha been carefully preserved, as a memorial of God's goodness to their fathers in the wilderness; but it was idle and wicked to burn incens to it. All helps to devotion, not warranted by the word of God interrupt the exercise of faith; they always lead to superstition an other dangerous evils. Human nature perverts every thing of this kind True faith needs not such aids; the word of God, daily thought upon an prayed over, is all the outward help we need.
