Adam Clarke on 2 Kings 23:2

The king went up into the house of the Lord - Here is another very singular circumstance. The high priest, scribes, priest, and prophets, are gathered together, with all the elders of the people, and the king himself reads the book of the covenant which had been lately found! It is strange that either the high priest, Jeremiah, Zephaniah, or some other of the prophets, who were certainly there present, did not read the sacred book! It is likely that the king considered himself a mediator between God and them, and therefore read and made the covenant.
