XAn exerpt from this morning's second reading at Vigils:
There are times when evils become the occasion of blessings and when God causes good results to follow from the sinful designs of men. A manifest example of this is the case of Joseph, whom his brothers, moved by jealousy, sold to the Ishmaelites for twenty pieces of silver. As things turned out, this crime against Joseph marked the beginning of all manner of benefits for the father and brothers of Joseph and for the whole land of Egypt, so that Joseph could later say to his brothers: "Even though you meant harm to me, God meant it for good."
-- St. Jerome
