'Sun' in the Bible

Every morning they gathered it, according to what each needed to eat; and when the sun became hot, it melted.

When Moses' hands became heavy, they took a stone and put it under him, and he sat on it. Aaron and Hur supported his hands, one on one side and one on the other, and so his hands were steady until the sun went down.

but if the sun has risen on him, then it is a capital crime in that case. A thief shall certainly make restitution, but if he has nothing, he is to be sold for his theft.
