2 Kings 23:21
The king commanded all the people, saying, 'Keep the passover to the LORD your God as prescribed in this book of the covenant' — Josiah commands the celebration of Passover (הַפְּסַח, *ha-Pesach*) according to the discovered law. Passover, the foundational covenant festival commemorating the Exodus redemption, becomes a focus of Josiah's reformation. The restoration of Passover practice indicates return to covenantal fundamentals.
