2 Chronicles 30:5

So they established a decree They fixed a resolution; to make proclamation throughout all Israel Hezekiah, it is certain, had no right to invite Hoshea's subjects to repair to Jerusalem, to the celebration of his passover; yet for the doing of this we may well presume that he had encouragement from Hoshea himself; who, as to the matter of religion, has a better character in Scripture than any of his predecessors, from the time of the division of the two kingdoms. But the truth was, that both the golden calves, which had caused this political separation, were now taken away; that of Dan by Tiglath-pileser, and that of Beth-el by his son Shalmaneser; and therefore some of the apostate Israelites, being thus deprived of their idols, began to return to the Lord, and to go up to Jerusalem to worship, some time before Hezekiah made them this invitation to his passover. See Prideaux and Dodd. They had not done it of a long time, &c., as it was written In such a manner as God had commanded them to keep it. Indeed, the ten tribes had never kept it since the division of the kingdom by Jeroboam; at least, not in the way in which Moses had prescribed, being hindered by his threatening interdicts from going to Jerusalem; where only it could be kept according to the law. And as for Judah, it appears, from 2 Chronicles 30:26, that they had never kept this feast with such solemnity since the time of Solomon.
