The sacrifice of the wicked is abomination: how much more, when he bringeth it with a wicked mind?
– Proverbs 21:27
[T]he word for abomination means disgusting, or detestable. Here it refers to a form of ritual worship that God hates. The first phrase echoes Proverbs 15:8 and the issue is the odious nature of hypocritical worship. Getting the outward form right is meaningless when the heart is not right (1 Samuel 15:22-23). In the second phrase, wicked mind refers to an evil intent, or plan. We could view this as an attempt to bribe God to overlook unrighteousness, or an attempt to entice God to deliver the wicked one through payment apart from repentance and faith. However, God refuses to hear those who will not hear him (Proverbs 28:9).
