9Speak not before the ears of a fool; for he will despise the intelligence of thy words.
10Remove not the ancient landmark, and into the fields of the fatherless must thou not enter;
11For their redeemer is strong; he will indeed plead their cause with thee.
12Apply thy heart unto instruction, and thy ears to the sayings of knowledge.
Proverbs 23
