Matthew Henry on 2 Samuel 13:21-29
What Solomon says of the beginning of strife is as true of the beginning of all sin, it is as the letting forth of water; when once the flood-gates are plucked up, an inundation follows; one mischief begets another, and it is hard to say what shall be in the end thereof.
