From which some having swerved have turned aside unto vain jangling; From which some having swerved - From which some, though they have pretended to aim at the τελος, scope, or mark, have missed that mark. This is the import of the original word αστοχησαντες.
Turned aside unto vain jangling - The original term, ματαιολογιαν, signifies empty or vain talking; discourses that turn to no profit; a great many words and little sense; and that sense not worth the pains of hearing. Such, indeed, is all preaching where Jesus Christ is not held forth.
