Proverbs 22:9

Here is, 1. The description of a charitable man; he has a bountiful eye, opposed to the evil eye (Pro 23:6) and the same with the single eye (Mat 6:22), - an eye that seeks out objects of charity, besides those that offer themselves, - an eye that, upon the sight of one in want and misery, affects the heart with compassion, - an eye that with the alms gives a pleasant look, which makes the alms doubly acceptable. He has also a liberal hand: He gives of his bread to those that need - his bread, the bread appointed for his own eating. He will rather abridge himself than see the poor perish for want; yet he does not give all his bread, but of his bread; the poor shall have their share with his own family. 2. The blessedness of such a man. The loins of the poor will bless them, all about him will speak well of him, and God himself will bless him, in answer to many a good prayer put up for him, and he shall be blessed.
