John Gill, on Prov 23:7

“Because like a soothsayer, and diviner, he thinketh that which he knoweth not. Eat and drink, will he say to thee: and his mind is not with thee.”

“For as he thinketh in his heart, so is he,.... He is not the man his mouth speaks or declares him to be, but what his heart thinks; which is discovered by his looks and actions, and by which he is to be judged of, and not by his words; eat and drink, saith he to thee, but his heart is not with thee; he bids you eat and drink, but he does not desire you should, at least but very sparingly; it is only a mere compliment, not a hearty welcome.”
