31 Heb “and if on the bed it (הוּא, hu’) is or on the vessel which she sits on it, when he touches it.…” The translation and meaning of this verse is a subject of much debate in the commentaries (see the summary in J. Milgrom, Leviticus [], 1:). It is difficult to determine what הוּא refers to, whether it means “he” referring to the one who does the touching, “it” for the furniture or the seat in v. 22, “she” referring to the woman herself (see היא rather than הוא), or perhaps anything that was lying on the furniture or the bed of vv. 21–22. The latter view is taken here (cf. J. E. Hartley, Leviticus [], ).
32 The accent suggest that “when he touches it” goes with the preceding line, but it seems to be better to take it as an introduction to what follows (see J. E. Hartley, Leviticus [], ).
