Numbers 9:11 Meaning and Commentary

Numbers 9:11

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 2 Chronicles 30:2 )

[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.

Numbers 9:11 In-Context

9 And the Lord spoke to Moses, saying,
10 Speak to the children of Israel, saying, Whatever man shall be unclean by reason of a dead body, or on a journey far off, among you, or among your posterity; he shall then keep the passover to the Lord,
11 in the second month, on the fourteenth day; in the evening they shall offer it, with unleavened bread and bitter herbs shall they eat it.
12 They shall not leave of it until the morrow, and they shall not break a bone of it; they shall sacrifice it according to the ordinance of the passover.
13 And whatsoever man shall be clean, and is not far off on a journey, and shall fail to keep the passover, that soul shall be cut off from his people, because he has not offered the gift to the Lord in its season: that man shall bear his iniquity.
