3 MOSEBOG 20:18

Om en Mand har Samleje med en Kvinde under hendes månedlige Svaghed og blotter hendes Blusel, idet han afdækker hendes Kilde, og hun afdækker sit Blods Kilde, da skal de begge udryddes af deres Folk.

And if a man shall lie with a woman having her sickness, and shall uncover her nakedness; he hath discovered her fountain, and she hath uncovered the fountain of her blood: and both of them shall be cut off from among their people.
