Matthew 5:8

I know also, my God, that thou triest the heart, and hast pleasure in uprightness. As for me, in the uprightness of mine heart I have willingly offered all these things: and now have I seen with joy thy people, which are present here, to offer willingly unto thee. O LORD God of Abraham, Isaac, and of Israel, our fathers, keep this for ever in the imagination of the thoughts of the heart of thy people, and prepare their heart unto thee: And give unto Solomon my son a perfect heart, to keep thy commandments, thy testimonies, and thy statutes, and to do all these things, and to build the palace, for the which I have made provision.

He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart.

With the pure thou wilt shew thyself pure; and with the froward thou wilt shew thyself froward.

He that hath clean hands, and a pure heart; who hath not lifted up his soul unto vanity, nor sworn deceitfully.

Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.

Truly God is good to Israel, even to such as are of a clean heart.

Woe unto you, scribes and Pharisees, hypocrites! for ye make clean the outside of the cup and of the platter, but within they are full of extortion and excess. Thou blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also. Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men's bones, and of all uncleanness. Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity.
