Leviticus 15:1-3
Leviticus 15:1-3 ESV
The LORD spoke to Moses and Aaron, saying, “Speak to the people of Israel and say to them, When any man has a discharge from his body, his discharge is unclean. And this is the law of his uncleanness for a discharge: whether his body runs with his discharge, or his body is blocked up by his discharge, it is his uncleanness.
