John Gill Commentary 2 Chronicles 26:17

"And Azariah the priest went in after him, and with him fourscore priests of Jehovah, that were valiant men:" — 2 Chronicles 26:17 (ASV)

And Azariah the priest went in after him
To hinder him from doing it, and to persuade him to go out. This was the high priest, as appears from (2 Chronicles 26:20) and is thought to be the same that is spoken of in (1 Chronicles 6:10)

and with him eighty priests of the Lord, that were valiant men ;
not only able bodied men, but men of spirit and courage, and zealous for the honour of God.
