You must not wrong or oppress a foreigner, for you were foreigners in the land of Egypt. You must not exploit any widow or orphan. If you do abuse them, when they cry out to me, I will surely heed their cry; my wrath will burn against you, and I will kill you with the sword, and your wives shall become widows and your children orphans.
(This is the only commandment given by God in Exodus that comes with an explicit promise of retribution by God Himself.)
-- Exodus 22
He conquers who endures.
Don't let life discourage you; everyone who got where he is had to begin where he was.
-- Richard L. Evans
What happens to a man is less significant than what happens within him.
