Proverbs 23:7-9

Young's Literal Translation

⁷ For as he hath thought in his soul, so [is] he, `Eat and drink,' saith he to thee, And his heart [is] not with thee.

⁸ Thy morsel thou hast eaten thou dost vomit up, And hast marred thy words that [are] sweet.

⁹ In the ears of a fool speak not, For he treadeth on the wisdom of thy words.
