'Brilliance' in the Bible

His body was like topaz, his face like the brilliance of lightning, his eyes like flaming torches, his arms and feet like the gleam of polished bronze, and the sound of his words like the sound of a multitude.

His brilliance is like light;rays are flashing from His hand.This is where His power is hidden.

When I came to you, brothers, announcing the testimony of God to you, I did not come with brilliance of speech or wisdom.
