“And when Aaron and all the children of Israel saw Moses, behold, the skinne of his face shone, and they were afraid to come nigh him.”

34:30 And Aaron and the children of Israel saw it, and were afraid - It not only dazzled their eyes, but struck such an awe upon them as obliged them to retire. Probably they doubted whether it was a token of God's favour, or of his displeasure.
