2 Chronicles 26:18

18 and they withstood `Uzziyah the king, and said to him, It pertains not to you, `Uzziyah, to burn incense to the LORD, but to the Kohanim the sons of Aharon, who are consecrated to burn incense: go out of the sanctuary; for you have trespassed; neither shall it be for your honor from the LORD God.

2 Chronicles 26:18 Meaning and Commentary

2 Chronicles 26:18

And they withstood Uzziah the king
They not only stood against him, but stood about him, surrounded him, so as to hinder him from approaching the altar of incense:

and said unto him, it appertaineth not unto thee, Uzziah, to burn
incense unto the Lord;
it did not belong to his office as a king, it was no part of it

but to the priests the sons of Aaron, that are consecrated to burn
incense;
and to them only; for even the Levites might not do it, only those of the tribe of Levi, that descended from Aaron, see ( Numbers 16:35 ) ,

go out of the sanctuary, for thou hast trespassed;
by going into that:

neither shall it be for thine honour from the Lord God;
but to his hurt, and be a brand of infamy upon him; for more is designed than is expressed, and as the event showed.

2 Chronicles 26:18 In-Context

16 But when he was strong, his heart was lifted up, so that he did corruptly, and he trespassed against the LORD his God; for he went into the temple of the LORD to burn incense on the altar of incense.
17 `Azaryah the Kohen went in after him, and with him eighty Kohanim of the LORD, who were valiant men:
18 and they withstood `Uzziyah the king, and said to him, It pertains not to you, `Uzziyah, to burn incense to the LORD, but to the Kohanim the sons of Aharon, who are consecrated to burn incense: go out of the sanctuary; for you have trespassed; neither shall it be for your honor from the LORD God.
19 Then `Uzziyah was angry; and he had a censer in his hand to burn incense; and while he was angry with the Kohanim, the leprosy broke forth in his forehead before the Kohanim in the house of the LORD, beside the altar of incense.
20 `Azaryah the chief Kohen, and all the Kohanim, looked on him, and, behold, he was leprous in his forehead, and they thrust him out quickly from there; yes, himself hurried also to go out, because the LORD had struck him.
