2 Chronicles 30:3 - Joseph Benson’s Commentary on the Old and New Testaments

For they could not keep it at that time Which God had appointed for it, both because the temple was not then purified and prepared, and also for two other reasons, which he here adds. The priests had not sanctified themselves sufficiently To wit, in such a manner as was fit, nor in such numbers as were necessary for the slaying and offering of so many thousands of paschal-offerings, as appears, because they were not sufficient for those offerings, which were comparatively few, 2 Chronicles 29:32-34. Neither had the people gathered themselves together, &c. As they used, and ought to do, at that time, from all places: which now they could not do, because neither was the matter agreed upon, nor were the people summoned thither, till the proper time was past.
