He who does a kindly act shall be recompensed tenfold.
Ye can never be righteous unless ye give away from that which ye love.
Traditions. The upper hand [which giveth] is better than the lower hand [which taketh].
God's creatures are the objects of His care, and He loveth best that man who is most helpful to them.
Proverbs. Do not be ashamed to give little, for it is less than that, if you give nothing.
If you give, give freely, and if you strike, strike boldly.
He who soweth kindness shall reap thanks.
What a man does for God is never lost.
