Psalm 18:20

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

Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.

That thine alms may be in secret: and thy Father which seeth in secret himself shall reward thee openly.

So that a man shall say, Verily there is a reward for the righteous: verily he is a God that judgeth in the earth.

The wicked worketh a deceitful work: but to him that soweth righteousness shall be a sure reward.

He shall deliver the island of the innocent: and it is delivered by the pureness of thine hands.

Behold, the LORD hath proclaimed unto the end of the world, Say ye to the daughter of Zion, Behold, thy salvation cometh; behold, his reward is with him, and his work before him.

For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;

The LORD shall judge the people: judge me, O LORD, according to my righteousness, and according to mine integrity that is in me.

Then I said, I have laboured in vain, I have spent my strength for nought, and in vain: yet surely my judgment is with the LORD, and my work with my God.

O LORD my God, if I have done this; if there be iniquity in my hands;

Therefore hath the LORD recompensed me according to my righteousness, according to the cleanness of my hands in his eyesight.

And he said to David, Thou art more righteous than I: for thou hast rewarded me good, whereas I have rewarded thee evil.

I will wash mine hands in innocency: so will I compass thine altar, O LORD:
