Leviticus 15:31 - Exposition

That they die not in their uncleanness, when they defile my tabernacle that is among them. The main purpose in the laws of uncleanness is to keep first God's house and then God's people free from the danger of defilement by foul things presenting themselves freely before him and among them. These foul things, symbolizing sinful things, create a ceremonial defilement symbolizing moral defilement.
