Proverbs 22:17-21

17Incline your ear, and hear the words of the wise, and apply your heart to my knowledge,

18for it will be pleasant if you keep them within you, if all of them are ready on your lips.

19That your trust may be in the Lord, I have made them known to you today, even to you.

20Have I not written for you thirty sayings of counsel and knowledge,

21to make you know what is right and true, that you may give a true answer to those who sent you?
