Numbers 9:7

9:7 And those men said to him, “We are ceremonially defiled by the dead body of a man; why are we kept back from offering the Lord’s offering at its appointed time among the Israelites?”

Numbers 9:13

9:13 But ¹  the man who is ceremonially clean, and was not on a journey, and fails ²  to keep the Passover, that person must be cut off from his people. ³  Because he did not bring the Lord’s offering at its appointed time, that man must bear his sin. ⁴ 

[9:13]  ¹ tn The disjunctive vav (ו) signals a contrastive clause here: “but the man” on the other hand….

[9:13]  ² tn The verb חָדַל (khadal) means “to cease; to leave off; to fail.” The implication here is that it is a person who simply neglects to do it. It does not indicate that he forgot, but more likely that he made the decision to leave it undone.

[9:13]  ³ sn The pronouncement of such a person’s penalty is that his life will be cut off from his people. There are at least three possible interpretations for this: physical death at the hand of the community (G. B. Gray, Numbers [ICC], 84-85), physical and/or spiritual death at the hand of God (J. Milgrom, “A Prolegomenon to Lev 17:11,” JBL 90 [1971]: 154-55), or excommunication or separation from the community (R. A. Cole, Exodus [TOTC], 109). The direct intervention of God seem to be the most likely in view of the lack of directions for the community to follow. Excommunication from the camp in the wilderness would have been tantamount to a death sentence by the community, and so there really are just two views.

[9:13]  ⁴ tn The word for “sin” here should be interpreted to mean the consequences of his sin (so a metonymy of effect). Whoever willingly violates the Law will have to pay the consequences.
