Leviticus 15:13

And when the one with a discharge is cleansed of his discharge , then he shall count for himself seven days for his cleansing , and wash his clothes . And he shall bathe his body in fresh water and shall be clean .

“‘When a man is cleansed from his discharge, he is to count off seven days for his ceremonial cleansing; he must wash his clothes and bathe himself with fresh water, and he will be clean.

And when he that hath an issue is cleansed of his issue; then he shall number to himself seven days for his cleansing, and wash his clothes, and bathe his flesh in running water, and shall be clean.
