Imamat 15:13

“Setelah tujuh hari sembuh dari penyakitnya, dia akan menjalani penyucian. Dia harus mencuci pakaiannya dan mandi di air mengalir. Sesudah itu dia tidak lagi najis.

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.
