Proverbs 19:8

Loveth his own soul, or loveth himself, because he procures great good to his soul, or to himself, as it follows; as sinners, on the contrary, are said to hate their souls, Proverbs 29:24, because they bring mischief upon them. That keepeth understanding; that observeth and carefully practiseth its precepts, as that phrase is commonly used. Shall find good; shall have great benefit by it, both for his conduct in this life, and for his happiness in the next.
