Detestable things are objects or practices regarded with abhorrence. In Scripture the term especially concerns idols and things associated with idolatry, as well as creatures and foods classified as ceremonially unclean.
The word is repeatedly applied to idol worship and its objects. It also describes forbidden creatures, including certain water animals, birds, winged insects, and creeping things. Eating such animals made a person detestable, and idolatrous objects were not to be appropriated for private use.
The terms translated detestable and abomination overlap in meaning. One group is associated particularly with idolatry; another concerns ceremonial uncleanness under the law’s food regulations.
