'Boldness' in the Bible

Now [when they] saw the boldness of Peter and John, and understood that they were uneducated and untrained men, they were astonished, and recognized them, that they had been with Jesus.

And now, Lord, concern yourself with their threats and grant your slaves to speak your message with all boldness,

And [when] they had prayed, the place in which they were gathered was shaken, and they were all filled with the Holy Spirit and began to speak the word of God with boldness.

proclaiming the kingdom of God and teaching the [things] concerning the Lord Jesus Christ with all boldness, without hindrance.
