⁹ The heart is deceitful above all things, and desperately wicked: who can know it?

¹⁰ I the Lord search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.

³⁴ O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

³⁵ A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.
