³ tn The initial seven days after the birth of a son were days of blood impurity for the woman as if she were having her menstrual period. Her impurity was contagious during this period, so no one should touch her or even furniture on which she has sat or reclined (Lev 15:19-23), lest they too become impure. Even her husband would become impure for seven days if he had sexual intercourse with her during this time (Lev 15:24; cf. 18:19). The next thirty-three days were either “days of purification, purifying” or “days of purity,” depending on how one understands the abstract noun טֹהֳרָה (toharah, “purification, purity”) in this context. During this time the woman could not touch anything holy or enter the sanctuary, but she was no longer contagious like she had been during the first seven days. She could engage in normal everyday life, including sexual intercourse, without fear of contaminating anyone else (B. A. Levine, Leviticus [JPSTC], 73-74; cf. J. Milgrom, Leviticus [AB], 1:749-50). Thus, in a sense, the thirty-three days were a time of blood “purity” (cf. the present translation) as compared to the previous seven days of blood “impurity,” but they were also a time of blood “purification” (or “purifying”) as compared to the time after the thirty-three days, when the blood atonement had been made and she was pronounced “clean” by the priest (see vv. 6-8 below). In other words, the thirty-three day period was a time of “blood” (flow), but this was “pure blood,” as opposed to the blood of the first seven days.
