Deuteronomy 22:22

If a man be found lying with a woman married to an husband,
&c.]. 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; (See Gill on 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; (See Gill on Deuteronomy 22:21).
