17Pay attention and listen to the words of the wise, and think carefully about my teachings—
18for it's good to keep them in mind so you can be ready to share them.
19I'm explaining this to you today so you can trust in the Lord—yes, you!
20Haven't I written down for you thirty sayings of advice and wisdom?
21They are to make it clear to you what's right and true, so you can give a truthful explanation to those who sent you.
