Leviticus 15:24

And if any man lies with her and her menstrual impurity comes upon him, he shall be unclean seven days , and every bed on which he lies shall be unclean .

“‘If a man has sexual relations with her and her monthly flow touches him, he will be unclean for seven days; any bed he lies on will be unclean.

And if any man lie with her at all, and her flowers be upon him, he shall be unclean seven days; and all the bed whereon he lieth shall be unclean.
