19. Also thou shalt not approach unto a woman to uncover her nakedness as long as she is put apart for her uncleanness.
19. Ad mulierem in segregatione immunditiae suae non accedes, revelando turpitudinem ejus.
18. 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.
18. Quicunque dormierit cum meretrice aegra, et revelaverit turpitudinem ejus, fontem ejus discooperuerit, ipsa etiam revelaverit fontem sanguinis sui: succidentur ambo e medio populi sui.
This precept2 has no other tendency than that believers should be kept far from all filthiness, and that chastity may flourish among them. It is indeed true that a woman, under these circumstances, is withheld from connection with a man by the very foulness of the disease, whilst there is also danger of contagion; but God rather chooses here to be an instructor in decency to His people, than to perform the office of a physician. It must be remembered, therefore, that men are warned against all indelicacy, which is abhorrent to the natural sense; and, by synecdoche, married persons are exhorted to restrain themselves from all immodest lasciviousness, and that the husband should enjoy his wife's embraces with delicacy and propriety.
