Leviticus 15:19-21

Young's Literal Translation

¹⁹ `And when a woman hath an issue -- blood is her issue in her flesh -- seven days she is in her separation, and any one who is coming against her is unclean till the evening.

²⁰ `And anything on which she lieth in her separation is unclean, and anything on which she sitteth is unclean;

²¹ and any one who is coming against her bed doth wash his garments, and hath bathed with water, and been unclean till the evening.
