Deuteronomy 22:22

If a man be found lying with a woman married to an husband,..... This law respects adultery, and is the same with that in

Leviticus 20:10

then they shall both of them die; with the strangling of a napkin, as the Targum of Jonathan, which is the death such persons were put to; and is always meant when death is simply spoken of, and it is not specified what death; Leviticus 20:10:

both the man that lay with the woman, and the woman; they were both to die, and to die the same death:

so shalt thou put away evil from Israel; such that do it, as the above Targum; Deuteronomy 22:21.
