11 For when a man is dead, he shall inherit creeping things, beasts, and worms.
12 The beginning of pride is when one departeth from God, and his heart is turned away from his Maker.
13 For pride is the beginning of sin, and he that hath it shall pour out abomination: and therefore the Lord brought upon them strange calamities, and overthrew them utterly.
