The book of Leviticus contains two series of prohibitions for a precise reason. Much of Leviticus (as well as Numbers and Deuteronomy) is given over to specific prohibitions that the nation of Israel was to observe as a “special people unto me.” Whether these prohibitions concerned eating of particular foods, wearing of specific garments, or other ceremonial considerations, the Lord consistently told Israel that such were unclean [or abomination] (Leviticus:11:7, etc.). This is one kind of prohibition, clearly applicable to Israel. On the other hand, issues such as adultery, sorcery, child sacrifice, bestiality, incest, homosexuality, etc., are said to be abomination (period). Penalties against those who commit these things are assessed because of God’s judgment (Leviticus:18:4). As to the punishment, Jesus’ actions concerning the woman taken in adultery (John:8:3) show that the law of Israel is not enforced in today’s day of grace.
"And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you."
