The later Jews speak of this as the "little Passover." Coming, as it did, a month after the proper Passover, it afforded ample time for a man to purify himself from legal defilement, as also to return from any but a very distant journey. Compare Hezekiah's act 2-Chronicles 30:1-3.
The fourteenth day of the (e) second month at even they shall keep it, [and] eat it with unleavened bread and bitter [herbs].
(e) So that the unclean and those who are not at home, have a month longer granted to them.
The fourteenth day of the second month at even they shall keep it,.... The mouth Ijar, as the Targum of Jonathan, which answers to part of our April and part of May; so that there was a month allowed for those that were defiled to cleanse themselves; and for those on a journey to return home and prepare for the passover, which was not to be totally omitted, nor deferred any longer; and it was to be kept on the same day of the month, and at the same time of the day the first passover was observed; still the more to keep in mind the saving of their firstborn; and their deliverance out of Egypt at that time: an instance of keeping such a passover we have in 2-Chronicles 30:1, &c.
and eat it with unleavened bread and bitter herbs; in the same manner as the first passover was eaten, Exodus 12:8; only no mention is made of keeping the feast of unleavened bread seven days, which some think those were not obliged unto at this time, only to keep the feast of the passover.
