He that giveth unto the poor shall not lack,.... That gives alms unto them, relieves them in their distress, supplies them with money, food, or clothes, and does it cheerfully, largely, and liberally, as the case requires; such an one shall not want any good thing; he shall not be the poorer for what he gives; he shall not miss it, nor his substance be diminished; he shall not come to poverty and want, yea, he shall be enriched, and his substance increased, for more is intended than is expressed.
Jarchi interprets this of a wise man not restraining doctrine from a disciple, but giving it to him liberally;but he that hideth his eyes; that is, from the poor, as the Targum and Syriac version add; that does not care to see his person, to behold his miseries, or know his case, lest his heart should be moved with compassion, and should draw out anything from him; see Isa 58:7.
