John Gill Commentary 2 Chronicles 29:20

"Then Hezekiah the king arose early, and gathered the princes of the city, and went up to the house of Jehovah." — 2 Chronicles 29:20 (ASV)

Then Hezekiah the king rose early
Took the first opportunity to attend the worship of God, and set an example to his people: and gathered the rulers of the city ;
the elders of the people, the chief magistrates in Jerusalem: and went up to the house of the Lord ;
the temple, to worship there.
