II Chronicles 30:7

Destruction of the idols and the altars of the high places. Provisions for the ordering and maintenance of the temple worship, and the attendants upon it. - Ch2 31:1. At the conclusion of the festival, all the Israelites who had been present at the feast (הנּמצאים כּל־שׂראל to be understood as in Ch2 30:21) went into the cities of Judah, and destroyed all the idols, high places, and altars not only in Judah and Benjamin (the southern kingdom), but also in Ephraim and Manasseh (the domain of the ten tribes), utterly (עד־לככּה, cf. Ch2 24:10), and only then returned each to his home; cf. Kg2 18:4.

In this chapter we have an account of the solemn passover which Hezekiah kept in the first year of his reign. I. The consultation about it, and the resolution he and his people came to for the observance of it (Ch2 30:2-5). II. The invitation he sent to Judah and Israel to come and keep it (Ch2 30:1, Ch2 30:6-12). III. The joyful celebration of it (Ch2 30:13-27). By this the reformation, set on foot in the foregoing chapter, was greatly advanced and established, and that nail in God's holy place clenched.
