2 Chronicles 29:31
Then Hezekiah answered and said, Now ye have consecrated yourselves unto the LORD, come near and bring sacrifices and thank offerings into the house of the LORD. And the congregation brought in sacrifices and thank offerings; and as many as were of a free heart burnt offerings.
The verse belongs to Hezekiah's reopening of the temple after its cleansing and purification and the restoration of its sacred vessels and worship. He began this restoration immediately upon coming to the throne at twenty-five, after a season of great decline in temporal affairs and morals and idolatry under the bad influence of his father Ahaz and his grandfather Jotham, having been given a pious mould through the influence of his mother. The work involved clearing away years of accumulated rubbish and re-establishing the worship of the true God, and it required ability and determination because evil beliefs and practices still held the people.
After the priests and Levites had consecrated themselves and finished the offering and the singing and worship, Hezekiah told those now consecrated to come near and bring sacrifices and thank offerings into the house of the Lord. The congregation responded by bringing in sacrifices and thank offerings, and as many as were of a free and willing heart brought burnt offerings. Their worship and giving was a willing response to renewed devotion to God, with the freewill burnt offerings reflecting willing participation by those whose hearts moved them freely.
The consecration and bringing of sacrifices and thank offerings belongs to a great fourteen-day Passover festival to which he sent letters by messengers from city to city throughout the northern kingdom inviting the people to forsake idols and return to God. Some came and others mocked, with many sacrifices offered in great gladness as the greatest revival since Solomon, followed under his direction by breaking down idols, cutting down groves, and destroying high places and altars. In this he is counted among the good kings who honored the Lord by restoring the work of the temple and the worship of Jehovah, and those who honor God He will honor. Seeking God with the whole heart brought help to His people, so his faithful course in restoring worship after the nation's idolatry pleased God and prepared the way for blessing. His action is an example of a king taking the lead in a national religious revival and of civil and religious authority working together in the religious life of the nation.
