'Blameless' in the Bible

so that you may be able to choose what is best and be pure and blameless until the day when the Messiah returns,

so that you may be blameless and innocent, God's children without any faults among a crooked and perverse generation, among whom you shine like stars in the world

As for my zeal, I was a persecutor of the church. As far as righteousness in the Law is concerned, I was blameless.
