At that time. — The time when the Temple had just been reopened (2 Chronicles 29:8), in the first month of Hezekiah’s first year. The Purification of the Temple was not completed until the 16th of Nisan (2 Chronicles 29:17); but perhaps the Passover would have been held, had not the hindrances here mentioned prevented it. (See 2 Chronicles 29:34).
Sufficiently. — Lĕmaddày. Literally, unto what was enough (lĕ-mah-dày), an expression only met with here. (Comp. a similar formation, 1 Chronicles 15:13.) The meaning is that a sufficient number of priests had not observed the legal ceremonies of self-purification in time to hold Passover in Nisan.
