Psalms 19:13

Presumptuous sin. — The Heb., from root meaning to “boil up” or “over,” is properly masculine, and always elsewhere means proud or arrogant men. (So Symmachus and Aquila.) Hence here explain, “Keep thy servant from the companionship of arrogant men, so that they may not get dominion over me, and lead me away from thy Law.”

The great transgression. — Rather, a great transgression, though even without the article it is possible the particular sin of idolatry is intended.
