2 Chronicles 30:5

So they established a decree to make proclamation throughout all Israel, from Beer-sheba even to Dan, that they should come to keep the passover unto the LORD God of Israel at Jerusalem: for they had not done it of a long time in such sort as it was written.

Hezekiah established a decree for a proclamation to go throughout all Israel, from Beer-sheba even to Dan, inviting the people to come to Jerusalem to keep the Passover unto the Lord God of Israel. The reason stated was that the Passover had not been kept nationally for a long time in the proper manner prescribed in the written ordinance. The decree came at the start of Hezekiah's reign, in the third year of Hoshea, as soon as the reforms in the temple service at Jerusalem were begun. It followed the good beginning made at the purification of the temple and belongs to the account of his first Passover.

The call went not only to Judah and Benjamin but to all the northern tribes, despite the division between Israel and Judah. Both Israel and Judah took part in the broader movement that followed the purification of the temple. It came when the northern kingdom had been broken by Assyria and reduced to a feeble remnant soon to be swept away. In zeal to make the temple services a real blessing to the people, Hezekiah determined to revive the ancient custom of gathering the Israelites together for the Passover feast.

During that Passover, arrangements were made for the priests to read the law publicly to the people each day. Observing the Mosaic statutes, especially those in the book of the covenant in Deuteronomy, contributed to the prosperity of Hezekiah's reign. The invitation was an act of mercy giving the northern Israelites another opportunity to turn from idolatry and return to God. Those invited were urged to yield to the Lord rather than remain stubborn, with the promise that He would receive those who returned and show compassion toward their people in captivity.

The verse serves as a call for God's people to come together in renewed worship and wholehearted commitment to the Lord.
