The words of his mouth are iniquity and deceit Are wicked and deceitful. He hath left off to be wise and to do good Once he had some degrees of wisdom, and did things that were apparently good, and seemed to be under the government of religion: but now he is an open apostate from that which he once professed. He deviseth mischief upon his bed Freely from his own inclination, when none are present to provoke him to it. He setteth himself in a way that is not good He doth not repent of his wicked devices, but resolutely proceeds to execute them, and persists therein. He abhorreth not evil Though he sometimes professes to feel remorse for his conduct, and desists for a time from his evil practices, yet he does not truly repent of, nor abhor them, and therefore is ready to return to them when any occasion offers itself.
