'Thick' in the Bible

And the Lord did this. Thick swarms of flies went into Pharaoh’s palace and his officials’ houses. Throughout Egypt the land was ruined because of the swarms of flies.

So Moses stretched out his hand toward heaven, and there was thick darkness throughout the land of Egypt for three days.

On the third day, when morning came, there was thunder and lightning, a thick cloud on the mountain, and a loud trumpet sound, so that all the people in the camp shuddered.

And the people remained standing at a distance as Moses approached the thick darkness where God was.
