3 MOSEBOG 15:13

Men når den, der lider af Flåd, bliver ren for sit Flåd, skal han tælle syv Dage frem, fra den Dag han bliver ren, og så tvætte sine Klæder og bade sit Legeme i rindende Vand; så er han ren.

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.
