'They Were Afraid' in the Bible

Then people went out to see what had happened. They came to Jesus, and found the man from whom the demons had gone out, sitting at Jesus' feet, clothed and in his right mind; and they were afraid.

While he said these things, a cloud came and overshadowed them, and they were afraid as they entered into the cloud.

But they did not understand this saying. It was concealed from them, that they should not perceive it, and they were afraid to ask him about this saying.
