“And the king … read in their hearing all the words of the Book of the Covenant” (23:2). Manasseh’s grandson, Josiah, began his reign by repairing the neglected Temple. During the construction, the forgotten Book of the Law (Covenant) was discovered, and when Josiah read it, he grieved over how far God’s people had strayed (ch 22). Josiah pulled out the idols from God’s Temple, burned them, cleansed the whole land, and led the people in observing Passover.
King Josiah was too late to stop the consequences of generational sin, and Jerusalem would soon be destroyed. However, Josiah took responsibility for his own generation, passionately lifting up God’s name all over the land (23:25).
