Bow down thine ear, and hear the words of the wise, and apply thine heart unto my knowledge. Bow down thine ear - From this to the end of Proverbs 22:21 are contained, not proverbs, but directions how to profit by that which wisdom has already delivered; the nature of the instruction, and the end for which it was given.
I shall give a paraphrase of this very important passage: -
I. Solomon addresses his pupils on the use of his past teachings. See on Proverbs 22:6 (note).
1. The wise man speaks; and all his words, not merely his sentiments, are to be carefully heard.
2. He speaks knowledge - gives doctrines true in themselves, and confirmed by observation and experience.
3. These are to be heard with humility and deep attention: "Bow down thine ear."
4. They must not only be heard, but meditated and pondered: "Apply thine heart to my knowledge."
