Proverbs 22:17-21 RSV

17 Incline your ear, and hear the words of the wise, and apply your mind to my knowledge;
18 for it will be pleasant if you keep them within you, if all of them are ready on your lips.
19 That your trust may be in the LORD, I have made them known to you today, even to you.
20 Have I not written for you thirty sayings of admonition and knowledge,
21 to show you what is right and true, that you may give a true answer to those who sent you?
