'Fearlessly' in the Bible

He began to speak out fearlessly in the synagogue, but when Priscilla and Aquila heard him, they took him aside and explained the way of God to him more accurately.

So Paul entered the synagogue and spoke out fearlessly for three months, addressing and convincing them about the kingdom of God.

and most of the brothers and sisters, having confidence in the Lord because of my imprisonment, now more than ever dare to speak the word fearlessly.
