Read the Bible

I will sing of your love and justice;
  to you, O Lord, I will sing praise.
I will be careful to lead a blameless life-
  when will you come to me?
I will walk in my house
  with blameless heart.
I will set before my eyes
  no vile thing.
The deeds of faithless men I hate;
  they will not cling to me.
Men of perverse heart shall be far from me;
  I will have nothing to do with evil.
Whoever slanders his neighbor in secret,
  him will I put to silence;
whoever has haughty eyes and a proud heart,
  him will I not endure.
My eyes will be on the faithful in the land,
  that they may dwell with me;
he whose walk is blameless
  will minister to me.
No one who practices deceit
  will dwell in my house;
no one who speaks falsely
  will stand in my presence.
Every morning I will put to silence
  all the wicked in the land;
I will cut off every evildoer
  from the city of the Lord.
