Matthew Poole and continuators on Ecclesiastes 10:13

13 The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness .

All his talk from the beginning to the end is foolish and mischievous, and the more he talks, the more doth his folly appear, he proceeds from evil to worse, and adds wilfulness to his weakness, and never desists till he hath done mischief to himself or to others.
