In Leviticus 15:19 and 24 (JPS), we are told: “And if a woman have an issue, and her issue in her flesh be blood, she shall be put apart seven days: and whosoever toucheth her shall be unclean until the even… And if any man lie with her, and her impurity be upon him, he shall be unclean seven days; and every bed whereon he lieth shall be unclean."
Next, Leviticus 18:19 warns: "And thou shalt not approach unto a woman to uncover her nakedness, as long as she is impure by her uncleanness."
Finally, Leviticus 20:18 states: "And if a man shall lie with a woman having her sickness, and shall uncover her nakedness--he hath made naked her fountain, and she hath uncovered the fountain of her blood--both of them shall be cut off from among their people."
It seems to go from warning to death penalty. Could someone explain this?
Further more, it is something evil to God it seems: Ezekiel 22:10 and Ezekiel 18:5-6
