'Boldness' in the Bible

Now when they beheld the boldness of Peter and John, and had perceived that they were unlearned and ignorant men, they marvelled; and they took knowledge of them, that they had been with Jesus.

And now, Lord, look upon their threatenings: and grant unto thy servants to speak thy word with all boldness,

And when they had prayed, the place was shaken wherein they were gathered together; and they were all filled with the Holy Spirit, and they spake the word of God with boldness.

preaching the kingdom of God, and teaching the things concerning the Lord Jesus Christ with all boldness, none forbidding him.
