'Emboldened' in the Bible

Joseph of Arimathaea, an honourable councillor, who also himself was awaiting the kingdom of God, coming, emboldened himself and went in to Pilate and begged the body of Jesus.

For if any one see thee, who hast knowledge, sitting at table in an idol-house, shall not his conscience, he being weak, be emboldened to eat the things sacrificed to the idol?
