'Courageously' in the Bible

Edom will be a captive; Seir, its enemies, will be a captive, and Israel [will be] acting {courageously}.

Joseph of Arimathea, a prominent member of the council who was also himself looking forward to the kingdom of God, came acting courageously [and] went in to Pilate and asked for the body of Jesus.

Be on the alert, stand firm in the faith, act courageously, be strong.
