Proverbs 15:15 - Matthew Poole's English Annotations on the Holy Bible

Of the afflicted; of the troubled in mind or heart, as this general expression may very fitly be restrained from the following clause. Are evil; tedious and uncomfortable; he takes no content in any time or thing. Of a merry heart, Heb. of a good heart, i.e. composed, and quiet, and contented. Hath a continual feast; hath constant satisfaction and delight in all conditions, yea, even in affliction.
