1 Samuel 15:20

And Samuel came to Saul: and Saul said unto him, Blessed be thou of the LORD: I have performed the commandment of the LORD.

The young man saith unto him, All these things have I kept from my youth up: what lack I yet?

For they being ignorant of God’s righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.

And he took Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword.

The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican.

But he, willing to justify himself, said unto Jesus, And who is my neighbour?

Wilt thou also disannul my judgment? wilt thou condemn me, that thou mayest be righteous?

I am clean without transgression, I am innocent; neither is there iniquity in me.

Thinkest thou this to be right, that thou saidst, My righteousness is more than God’s?

For Job hath said, I am righteous: and God hath taken away my judgment.
