Isaiah
Isaiah 58:7ESV·traditional attribution

Is it not to share your bread with the hungry and bring the homeless poor into your house; when you see the naked, to cover him, and not to hide yourself from your own flesh?

Is it not to deal thy bread to the hungry?.... Or "to break" (f) it, divide it, and communicate it to them; that which is "bread", food fit to eat, wholesome and nourishing; which is thine, and not another's; which thou hast saved by fasting, and therefore should not be laid up, but given away; and that not to the rich, who need it not...

deal--distribute (Job 31:16-21). cast out--rather, reduced [HORSLEY]. naked . . . cover him-- (Mat 25:36). hide . . . thyself--means to be strange towards them, and not to relieve them in their poverty (Mat 15:5). flesh--kindred (Gen 29:14). Also brethren in common descent from Adam, and brethren in Christ (Jam 2:15).
