'Appearance' in the Bible

And on the day that the tabernacle was set up, the cloud covered the tabernacle of the tent of testimony; and at even it was upon the tabernacle as the appearance of fire, until the morning.

So it was continually: the cloud covered it, and at night it was as the appearance of fire.

And the manna was as coriander seed, and its appearance as the appearance of bdellium.
