Leviticus 20:19 Meaning and Commentary

Leviticus 20:19

And thou shalt not uncover the nakedness of thy mother's
sister, nor of thy father's sister
An aunt either by mother or father's side, against which the law is, ( Leviticus 18:13 ) ; for he uncovereth his near kin;
as an aunt is to a man, and so an uncle to a woman, and both equally criminal; for it is a rule that holds good in all those cases, though not expressed, that what is binding upon one sex is upon the other, being in the same degree of relation, whether of consanguinity or affinity: they shall bear their iniquity;
"both" of them, as the Vulgate Latin version, the man and his aunt, and so a woman and her uncle; the guilt of their sin shall be upon them,
and the punishment of it be inflicted on them; either they should be cut off from their people, as before, or be childless, as in the following instances.

18 If a man sleeps with a menstruating woman and has sexual intercourse with her, he has exposed the source of her [flow], and she has uncovered the source of her blood. Both of them must be cut off from their people.
