'Boldness' in the Bible

Now when the men of the Sanhedrin (Jewish High Court) saw the confidence and boldness of Peter and John, and grasped the fact that they were uneducated and untrained [ordinary] men, they were astounded, and began to recognize that they had been with Jesus.

And when they had prayed, the place where they were meeting together was shaken [a sign of God’s presence]; and they were all filled with the Holy Spirit and began to speak the word of God with boldness and courage.

preaching and proclaiming the kingdom of God and teaching about the Lord Jesus Christ with all openness and boldness, unhindered and unrestrained.
