Matthew Poole and continuators on Lamentations 3:33

33 For he doth not afflict willingly, nor grieve the children of men .

In the Hebrew it is he doth not afflict from his heart, that is with pleasure and delight; or (which seemeth the best sense to me) not from his own meer motion without a cause given him from the persons afflicted. Hence Judgment is called Gods strange work; shewing Mercy is his proper natural work, which floweth from himself without any cause in the Creature. Judgment is his strange work to which he never proceedeth but when provoked, and as it were forced from the Creature, whence it followeth that he cannot delight in it.
