Psalms 101:3-6

I refuse to gaze on that which is vulgar. I despise works of evil people and anything that moves my heart away from you. I will not let evil hold me in its grip. Every perverse and crooked way I have put away from my heart, for I will have nothing to do with the deeds of darkness. I will silence those who secretly want to slander my friends, and I will not tolerate the proud and arrogant. My innermost circle will only be those who I know are pure and godly. They will be the only ones I allow to minister to me.
