Bible Notes Online - 2-Chronicles 30 - ESV
Commentary

v1: Hezekiah's desire was to see people from Judah and Israel return to the Lord. Since Israel was finally defeated some 6-7 years later, this was very timely, and the last chance for many to preserve their lives.

v2: There was provision in the law for people to celebrate the Passover in the second month, Num 9.6-14. Here, in effect, the whole nation was defiled.

v3-4: It was impossible for the people to celebrate the Passover in the first month, and no one had done so. Hezekiah had evidently consulted with the leaders, who had agreed to use the second month.

v5: The invitation was sent from Dan to Beersheba, taking in the whole of both Judah and Israel. An open letter was sent throughout the two kingdoms.

v6-9: A message calling the people to repentance and submission to God; see Ps 66.10-12. After the time of testing there was joy and "rich fulfilment". God would honour their repentance; Hezekiah had confidence in God's faithfulness.

v10-12: There were mixed responses from Israel. Some mocked the messengers, but other humbled themselves and went to Jerusalem.

Judah stands out as the tribe of loyalty to God, desiring to rid themselves of all vestiges of idolatry, and to worship God alone.

v13: A large crowd joined together in Jerusalem.

v14: A corporate act of rejecting idolatry.

v15-17: The Levites began proceedings, unaware of the large numbers that were ceremonially unclean.

v18-20: Those from Israel had not had opportunity to go through the ritual washing. Hezekiah reflected God's heart, that each one "who sets his heart on seeking God", would enjoy God's blessing. The Lord God would grant pardon and provide atonement, since they celebrated the Passover "contrary to what was written". The Lord God looks at the heart, "I desire mercy and not sacrifice" (Matt 9.13; 12.7).

v21-22: There was great gladness as the people celebrated for seven days. There was singing to the Lord, and teaching the knowledge of the Lord.

v23-27: After the seven days, the whole assembly agreed to celebrate for another seven days. A Passover on this scale had not happened since the time of Solomon, before the kingdom had been divided.
