Matthew 5:8

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

"Create in me a clean heart, O God; and renew a right spirit within me."

"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."

"Follow peace with all men, and holiness, without which no man shall see the Lord:"

"He that loveth pureness of heart, for the grace of his lips the king shall be his friend. for...: or, and hath grace in his lips"

"Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded."

"Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently:"

"But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy."

"Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled."
