'Appearance' in the Bible

And it came to pass, when I, even I Daniel, had seen the vision, that I sought to understand it; and, behold, there stood before me as the appearance of a man.

his body also was like the beryl, and his face as the appearance of lightning, and his eyes as flaming torches, and his arms and his feet like unto burnished brass, and the voice of his words like the voice of a multitude.

Then there touched me again one like the appearance of a man, and he strengthened me.
