The transgression of the wicked saith within my heart... — The literal rendering of the present Hebrew text is, An utterance of sin to the wicked within my heart. The common phrase rendered in our version, “Thus saith Jehovah,” is here imitated, “Thus saith sin.” “To the wicked” cannot, as some explain, mean “concerning the wicked.” The only possible meaning of the text as it stands is therefore, “Thus saith sin to (me) the wicked man in my heart.” But there can be no question that the psalmist wrote “in his heart,” since ail the ancient versions, with the exception of the Chaldee Paraphrase, followed this reading, and some MSS. still show it. This gives us a very fine sense. Sin is personified as the evil counsellor or prompter sitting in the heart of the wicked to suggest evil thoughts: Sin in the wicked man’s heart is his oracle. Conscience is on the wrong side.
There is no fear... — This is not the suggestion of sin just mentioned, but an explanation of the condition into which the wicked man has sunk. Impiety and irreverence have so corrupted his nature, that sin has become his oracle.
