John Gill Commentary Leviticus 20:13

"And if a man lie with mankind, as with womankind, both of them have committed abomination: they shall surely be put to death; their blood shall be upon them." — Leviticus 20:13 (ASV)

If a man lie also with mankind, as he lieth with a woman
Is guilty of the sin of sodomy, this is a breach of the law in (Leviticus 18:22);

both of them have committed an abomination;
he that lies, and he that is lain with, both consenting to perpetrate the abominable wickedness; which may well be called an abomination, being contrary to nature, and more than brutish, for nothing of that kind is to be found among brutes:

they shall surely be put to death;
if he that is lain with is not forced, as Aben Ezra observes:

their blood [shall be] upon them;
be slain by stoning, as the above Targum.
