Proverbs 4:23

⁴⁵The good man out of the good treasure of his heart brings out that which is good, and the evil man out of the evil treasure of his heart brings out that which is evil, for out of the abundance of the heart, his mouth speaks.

³⁴You offspring of vipers, how can you, being evil, speak good things? For out of the abundance of the heart, the mouth speaks. ³⁵The good man out of his good treasure^[+] brings out good things, and the evil man out of his evil treasure brings out evil things.

²¹For from within, out of the hearts of men, proceed evil thoughts, adulteries, sexual sins, murders, thefts, ²²covetings, wickedness, deceit, lustful desires, an evil eye, blasphemy, pride, and foolishness. ²³All these evil things come from within and defile the man.”

²³Search me, God, and know my heart. Try me, and know my thoughts. ²⁴See if there is any wicked way in me, and lead me in the everlasting way.

³He who guards his mouth guards his soul. One who opens wide his lips comes to ruin.

⁹The heart is deceitful above all things and it is exceedingly corrupt. Who can know it?

¹⁹For out of the heart come evil thoughts, murders, adulteries, sexual sins, thefts, false testimony, and blasphemies.

¹⁹Listen, my son, and be wise, and keep your heart on the right path!

²⁶One who trusts in himself is a fool; but one who walks in wisdom is kept safe.

³⁸Watch and pray, that you may not enter into temptation. The spirit indeed is willing, but the flesh is weak.”
