Leviticus 15:3-5

New International Version

³ Whether it continues flowing from his body or is blocked, it will make him unclean. This is how his discharge will bring about uncleanness:

⁴ “‘Any bed the man with a discharge lies on will be unclean, and anything he sits on will be unclean. ⁵ Anyone who touches his bed must wash their clothes^(A) and bathe with water,^(B) and they will be unclean till evening.^(C)
