'Pure' in the Bible

so that you can approve the things that are superior and can be pure and blameless in the day of Christ,

so that you may be blameless and pure, children of God who are faultless in a crooked and perverted generation, among whom you shine like stars in the world.

Finally brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable—if there is any moral excellence and if there is any praise—dwell on these things.
