'Afraid' in the Bible

The man replied, "Who made you a ruler and a judge over us? Are you planning to kill me like you killed that Egyptian?" Then Moses was afraid, thinking, "Surely what I did has become known."

He added, "I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob." Then Moses hid his face, because he was afraid to look at God.

When Aaron and all the Israelites saw Moses, the skin of his face shone; and they were afraid to approach him.
