Ulangan 23:10

23:10 If there is someone among you who is impure because of some nocturnal emission, ¹  he must leave the camp; he may not reenter it immediately.

Ulangan 29:15

29:15 but with whoever stands with us here today before the Lord our God as well as those not with us here today. ² 

[23:10]  ¹ tn Heb “nocturnal happening.” The Hebrew term קָרֶה (qareh) merely means “to happen” so the phrase here is euphemistic (a “night happening”) for some kind of bodily emission such as excrement or semen. Such otherwise normal physical functions rendered one ritually unclean whether accidental or not. See Lev 15:16-18; 22:4.

[29:15]  ² tn This is interpreted by some English versions as a reference to generations not yet born (cf. TEV, CEV, NLT).
