Keep thy heart with all diligence; for out of it are the issues of life.
(Pro 4:23)

A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.
(Luk 6:45)

He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.
(Pro 28:26)

The heart is deceitful above all things, and desperately wicked: who can know it? 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.
(Jer 17:9-10)
