If thou hast done foolishly in lifting up thyself, or if thou hast thought evil, lay thine hand upon thy mouth. Surely the churning of milk bringeth forth butter, and the wringing of the nose bringeth forth blood: so the forcing of wrath bringeth forth strife.
Agur, son of Jakeh (Proverbs 30:32-33)
In the day of prosperity be joyful, but in the day of adversity consider: God also hath set the one over against the other, to the end that man should find nothing after him.
King Solomon (Ecclesiastes 7:14)
