Proverbs 23:6-7 NASB
Do not eat the bread of a selfish person; or desire his delicacies;
For as he thinks within himself, so he is. He says to you, “Eat and drink!” But his heart is not with you.

Luke 6:45 NLT
A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart. What you say flows from what is in your heart.
