Proverbs 22:16-18

Complete Jewish Bible

¹⁶ Both oppressing the poor to enrich oneself
    and giving to the rich yield only loss.

¹⁷ Pay attention, and listen to the words of the wise;
    apply your heart to my knowledge;
¹⁸ for it is pleasant to keep them deep within you;
    have all of them ready on your lips.
