Proverbs 23:7-9

Amplified Bible

⁷ 
For as he thinks in his heart, so is he [in behavior—one who manipulates].
He says to you, “Eat and drink,”
Yet his heart is not with you [but it is begrudging the cost].
⁸ 
The morsel which you have eaten you will vomit up,
And you will waste your compliments.

⁹ 
Do not speak in the ears of a fool,
For he will despise the [godly] wisdom of your words.^(A)
