PROVERBS 23

4 Labour not to be rich: cease from thine own wisdom.
. . .
9 Speak not in the ears of a fool: for he will despise the wisdom of thy words.
. . .
12 Apply thine heart unto instruction, and thine ears to the words of knowledge.
. . .
19 Hear thou, my son, and be wise, and guide thine heart in the way.
. . .
23 Buy the truth, and sell it not; also wisdom, and instruction, and understanding.
