'Boldly' in the Bible

He was talking and arguing with the Hellenists (Greek-speaking Jews); but they were attempting to kill him.

And [at the same time] Paul and Barnabas spoke out boldly and confidently, saying, “It was necessary that God’s message [of salvation through faith in Christ] be spoken to you [Jews] first. Since you repudiate it and judge yourselves unworthy of eternal life, now we turn to the Gentiles.

So Paul and Barnabas stayed for a long time, speaking boldly and confidently for the Lord, who continued to testify to the word of His grace, granting that signs and wonders (attesting miracles) be done by them.

and he began to speak boldly and fearlessly in the synagogue. But when Priscilla and Aquila heard him, they took him aside and explained more accurately to him the way of God [and the full story of the life of Christ].

And he went into the synagogue and for three months spoke boldly, reasoning and arguing and persuading them about the kingdom of God.
