8. The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.
9. Speak not in the hearing of a fool; for he will despise the wisdom of thy words.
10. Remove not the ancient landmark; and enter not into the fields of the fatherless:
11. For their redeemer is strong; he shall plead their cause against thee.
12. Apply thine heart unto instruction, and thine ears to the words of knowledge.
