This refers to the laws Yahweh put in place regarding the woman's monthly menstrual cycle and childbirth.

Are these laws still in effect? Or have they been abolished? Were the women placed outside the camp as were the lepers? Or did they remain with their families?

Looking at these verses, how did they attend to their families? Are these only ceremonial and ritual? Does our salvation depend upon obedience to this? Exactly how would these things be applied today?
