Proverbs 23:5-9

⁵If thou shouldest fix thine eye upon him, he will disappear; for wings like an eagle's are prepared for him, and he returns to the house of his master.

⁶Sup not with an envious man, neither desire thou his meats:

⁷so he eats and drinks as if any one should swallow a hair, and do not bring him in to thyself, nor eat thy morsel with him:

⁸for he will vomit it up, and spoil thy fair words.

⁹Say nothing in the ears of a fool, lest at any time he sneer at thy wise words.
