17 Let your ear be bent down for hearing my words, and let your heart give thought to knowledge.
18 For it is a delight to keep them in your heart, to have them ready on your lips.
19 So that your faith may be in the Lord, I have made them clear to you this day, even to you.
20 Have I not put in writing for you thirty sayings, with wise suggestions and knowledge,
21 To make you see how certain are true words, so that you may give a true answer to those who put questions to you?
