to abhor: to find someone or something detestable and turn away from it in loathing
This is the verb behind the well-known noun for an abomination (toevah). To abhor something is to treat it as detestable and recoil from it. The loathing may be God's, a whole community's, or a single person's, and its object may be an idol, an enemy, a truth no one wants to hear, or even food a sick person can no longer stand.
The word covers a wide range of revulsion. God abhors the violent and the deceitful (Psalm 5:6), and in anger he can turn against his own people (Psalm 106:40). People abhor an idol devoted to destruction (Deuteronomy 7:26), a friend who has become a stranger (Job 19:19), or someone who tells them a truth they would rather silence (Amos 5:10). It can even be physical, as when a dying person's appetite fails and the soul loathes all food (Psalm 107:18).
The same word also runs the opposite direction. A person or thing can be the one abhorred, the object others find loathsome and shun. That is how it describes corrupt humanity (Job 15:16), a discarded corpse (Isaiah 14:19), and a command that struck a commander as detestable (1 Chronicles 21:6).
