Psalms 18:23-26

²³And I was upright before him, and I kept myself from sin.

²⁴Because of this the Lord has given me the reward of my righteousness, because my hands are clean in his eyes.

²⁵On him who has mercy you will have mercy; to the upright you will be upright;

²⁶He who is holy will see that you are holy; but to the man whose way is not straight you will be a hard judge.
