Lev 15:19-27 | KD | STEP | The menses of a woman . - “If a woman have an issue, (if) blood is her issue in her flesh, she shall be seven days in her uncleanness.” As the discharge does not last as a rule more than four or five days, the period of seven days was fixed on account of the significance of the number seven. In this condition she rendered every one who touched her unclean ( ), everything upon which she lay or sat ( ), every one who touched her bed or whatever she sat upon ( , ), also any one who touched the blood upon her bed or seat ( , where הוּא and בּו are to be referred to דּם); and they remained unclean till the evening, when they had to wash their clothes and bathe themselves.

‏ Leviticus 15:19-27

Lev 15:19-23 The menses of a woman. - “If a woman have an issue, (if) blood is her issue in her flesh, she shall be seven days in her uncleanness.” As the discharge does not last as a rule more than four or five days, the period of seven days was fixed on account of the significance of the number seven. In this condition she rendered every one who touched her unclean (Lev 15:19), everything upon which she lay or sat (Lev 15:20), every one who touched her bed or whatever she sat upon (Lev 15:21, Lev 15:22), also any one who touched the blood upon her bed or seat (Lev 15:23, where הוּא and בּו are to be referred to דּם); and they remained unclean till the evening, when they had to wash their clothes and bathe themselves. Lev 15:24

If a man lay with her and her uncleanness came upon him, he became unclean for seven days, and the bed upon which he lay became unclean as well. The meaning cannot be merely if he lie upon the same bed with her, but if he have conjugal intercourse, as is evident from Lev 20:18 and Num 5:13 (cf. Gen 26:10; Gen 34:2; Gen 35:22; 1Sa 2:22). It cannot be adduced as an objection to this explanation, which is the only admissible one, that according to Lev 18:19 and Lev 20:18 intercourse with a woman during her menses was an accursed crime, to be punished by extermination. For the law in Lev 20:18 refers partly to conjugal intercourse during the hemorrhage of a woman after child-birth, as the similarity of the words in Lev 20:18 and Lev 12:7 (דּמיה מקור) clearly proves, and to the case of a man attempting cohabitation with a woman during her menstruation. The verse before us, on the contrary, refers simply to the possibility of menstruation commencing during the act of conjugal intercourse, when the man would be involuntarily defiled through the unexpected uncleanness of the woman. Lev 15:25-27 Diseased issue from a woman. - If an issue of blood in a woman flowed many days away from (not in) the time of her monthly uncleanness, or if it flowed beyond her monthly uncleanness, she was to be unclean as long as her unclean issue continued, just as in the days of her monthly uncleanness, and she defiled her couch as well as everything upon which she sat, as in the other case, also every one who touched either her or these things.
