2 Chronicles 30:1

And Hezekiah sent to all Israel and Judah, to the entire congregation adhering to the worship of Jehovah, and wrote letters also to Ephraim and Manasseh, the chief tribes of the northern kingdom, as many of them as were left after the bulk of the people had been led into captivity by the king of Assyria, that they should come to the house of the Lord at Jerusalem to keep the Passover unto the Lord God of Israel, for he was anxious to restore the observance of the festival, as in ancient days.
