Deuteronomy 4:9

Take heed to thyself, and keep thy heart diligently: forget not any of the things, which thine eyes have seen, and let them not depart from thine heart all the days of thy life; and thou shalt teach thy sons and thy sons' sons,

Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons’ sons;

Only be careful, and keep your soul diligently, lest you forget the things which your eyes saw, and lest they depart from your heart all the days of your life; but make them known to your children and your children’s children—
