Jamieson, Fausset and Brown on Leviticus 18:29

29. the souls that commit them shall be cut off--This strong denunciatory language is applied to all the crimes specified in the chapter without distinction: to incest as truly as to bestiality, and to the eleven cases of affinity [Le 18:7-16], as fully as to the six of consanguinity [Le 18:17-20]. Death is the punishment sternly denounced against all of them. No language could be more explicit or universal; none could more strongly indicate intense loathing and abhorrence.
