Hezekiah and Josiah celebrate large-scale Passovers. Why? What are they being delivered from? In both cases, Passover is preceded by massive destruction of idols and idolatrous shrines. First, the humiliation of the “gods of Egypt” and then the Passover.

And that throws light back on the original Passover, which is not only about deliverance from the angel of death or from the tyrant Pharaoh, but a deliverance from Israel’s own devotion to Egypt’s gods.
