Keep the passover. — Hold a passover (2 Kings 23:22). (Comp. 2 Chronicles 35:1-19 for a more detailed account of this unique celebration.) Josiah had the precedent of Hezekiah for signalising his religious revolution by a solemn passover (2 Chronicles 30:1).
In the book of this covenant. — Rather, in this book of the covenant (2 Kings 23:2). The book was that which Hilkiah had found in the Temple, and which gave the impulse to the whole reforming movement. (The LXX. and Vulg. read, in the book of this covenant — a mere mistake.)
