Yet is there a sore plague, which I have seen under the sun: namely, riches kept to the hurt of him that hath them in possession.

Whoso removeth stones shall have travail withal; and he that heweth wood, shall be hurt therewith.

Wish the king no evil in thy thought, and speak no hurt of the rich in thy privy chamber; for a bird of the air shall betray thy voice, and with her feathers shall she betray thy words.
