"Administer of your substance unto him that standeth in need; and ye will not suffer that the beggar putteth
up his petition to you in vain, and turn him out to perish." 4:16
"Ye ought to impart of the substance that ye have one to another." 4:21
"Impart of your substance to the poor, every man according to that which he hath, such as feeding the hungry,
