Matthew Henry on 2 Chronicles 35:1-19
The destruction which Josiah made of idols and idolatry was more largely related in the Kings, but just mentioned here in the foregoing chapter (v. 33); but his solemnizing the passover, which was touched upon there (Kg2 23:21), is very particularly related here. Many were the feasts of the Lord, appointed by the ceremonial law, but the passover was the chief.
