What is the meaning of “And He donned charity like a coat of armor...”? Why is charity compared to a coat of armour?
To tell you that just as each scale combines to form a large coat of
armour, so with respect to giving charity each coin combines with all
others to comprise a large sum, that is, to be considered as a large
gift, reflecting more favorably on the donor.
One who gives a small coin to a pauper is blessed with six Heavenly blessings, and one who comforts him with words gets eleven blessing.
