2-я Паралипоменон 26:16

Jotham having ascended the throne at the age of twenty-five, reigned altogether in the spirit and power of his father, with the single limitation that he did not go into the sanctuary of Jahve (cf. Ch2 26:16.). This remark is not found in 2 Kings 15, because there Uzziah's intrusion into the temple is also omitted. The people still did corruptly (cf. Ch2 26:16). This refers, indeed, to the continuation of the worship in the high places, but hints also at the deep moral corruption which the prophets of that time censure (cf. especially Isa 2:5., Ch2 5:7.; Mic 1:5; Mic 2:1.).

Here is the only blot we find on the name of king Uzziah, and it is such a one as lies not on any other of the kings. Whoredom, murder, oppression, persecution, and especially idolatry, gave characters to the bad kings and some of them blemishes to the good ones, David himself not excepted, witness the matter of Uriah. But we find not Uzziah charged with any of these; and yet he transgressed against the Lord his God, and fell under the marks of his displeasure in consequence, not, as other kings, in vexatious wars or rebellions, but an incurable disease. I. His sin was invading the priest's office. The good way is one; by-paths are many. The transgression of his predecessors was forsaking the temple of the Lord, flying off from it (Ch2 24:18), and burning incense upon idolatrous altars, Ch2 25:14. His was intruding into the temple of the Lord further than was allowed him, and attempting him to burn incense upon the altar of God, for which, it is likely, he pretended an extraordinary zeal and affection. See how hard it is to avoid one extreme and not run into another. 1. That which was at the bottom of his sin was pride of heart, a lust that ruins more than any other whatsoever (Ch2 26:16): When he was strong (and he was marvellously helped by the good providence of God till he was so, Ch2 26:15), when he had grown very great and considerable in wealth, interest, and power, instead of lifting up the name of God in gratitude to him who had done so much for him, his heart was lifted up to his destruction. Thus the prosperity of fools, by puffing them up with pride, destroys them. Now that he had done so much business, and won so much honour, he began to think no business, no honour, too great or too good for him, no, not that of the priesthood Men's pretending to forbidden…

26:16-18 Uzziah’s leprosy was a judgment on the covenant violation of burning incense within the Temple, an activity reserved exclusively for priests (Exod 30:7-9; Num 16).
