Numbers 9:10

9:10 “Tell the Israelites, ‘If any of you or of your posterity become ceremonially defiled by touching a dead body, or are on a journey far away, then he may observe the Passover to the Lord.

Numbers 14:3

14:3 Why has the Lord brought us into this land only to be killed by the sword, that our wives and our children should become plunder? Wouldn’t it be better for us to return to Egypt?”

tn This sense is conveyed by the repetition of “man” – “if a man, a man becomes unclean.”

tn The perfect tense with vav (ו) consecutive functions as the equivalent of an imperfect tense. In the apodosis of this conditional sentence, the permission nuance fits well.
