Proverbs

4:23 Keep thy heart with all diligence; for out of it are the issues of life.
23:7 For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.

12:34 O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

6:45 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.

15:18 But those things which proceed out of the mouth come forth from the heart; and they defile the man.
19 For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:

10:10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.

1:14 But every man is tempted, when he is drawn away of his own lust, and enticed.
15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.

12:2 They speak vanity every one with his neighbour: with flattering lips and with a double heart do they speak.
55:21 The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords.

23:7 For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.

11:39 And the Lord said unto him, Now do ye Pharisees make clean the outside of the cup and the platter; but your inward part is full of ravening and wickedness.
43 Woe unto you, Pharisees! for ye love the uppermost seats in the synagogues, and greetings in the markets.

44:21 Shall not God search this out? for he knoweth the secrets of the heart.
139:13 For thou hast possessed my reins: thou hast covered me in my mother's womb.

15:11 Hell and destruction are before the LORD: how much more then the hearts of the children of men?

11:20 But, O LORD of hosts, that judgest righteously, that triest the reins and the heart, let me see thy vengeance on them: for unto thee have I revealed my cause.
17:10 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.

15:8 And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;

28 The heart of the righteous studieth to answer: but the mouth of the wicked poureth out evil things.

14:25 And thus are the secrets of his heart made manifest; and so falling down on his face he will worship God, and report that God is in you of a truth.

4:7 But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us.

12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
8:10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
10:22 Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.

4:1 Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin;
