Lev_20:25 Ye shall therefore put difference between clean beasts and unclean, and between unclean fowls and clean: and ye shall not make your souls abominable by beast, or by fowl, or by any manner of living thing that creepeth on the ground, which I have separated from you as unclean.
Ver. 25. Between clean beasts.] How much more then shall you abstain from those unlawful copulations, whereby men put off all manhood, degenerate into dogs? {Rom_1:27 Deu_23:182Sa_3:8}
