Proverbs 26:23-25 New King James Version (NKJV)

23. Fervent lips with a wicked heartAre like earthenware covered with silver dross.

24. He who hates, disguises it with his lips,And lays up deceit within himself;

25. When he speaks kindly, do not believe him,For there are seven abominations in his heart;
