'Courageously' in the Bible

Barnabas, however, introduced Saul to the apostles, telling them how on the road Saul had seen the Lord, who had spoken to him, and how courageously he had spoken in the name of Jesus in Damascus.

So he freely circulated among them in Jerusalem, speaking courageously in the name of the Lord.

Moreover, because of my imprisonment the Lord has caused most of the brothers to become confident to speak God's word more boldly and courageously than ever before.
