All the days of the afflicted are evil: but he that is of a merry heart hath a continual feast.
All the days of the afflicted are evil. Of those whose affliction causes them to lose a hopeful "heart," as the opposite clause requires, cf. Nehemiah 2:2.
But he that is of a merry heart (hath) a continual feast - literally, a 'continual marriage feast' (Judges 14:10), or 'a convivial feast, where drink is served up,' and which from beginning to end is all enjoyment. Joy and contentments within dispel outward sorrows, poverty, etc. (Ecclesiastes 9:7).
