'Blameless' in the Bible

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

That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;

Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
