'Deep' in the Bible

Inside the stand was a round opening that was a foot-and-a-half deep; it had a support that was two and one-quarter feet long. On the edge of the opening were carvings in square frames.

On top of each stand was a round opening three-quarters of a foot deep; there were also supports and frames on top of the stands.

At noon Elijah mocked them, "Yell louder! After all, he is a god; he may be deep in thought, or perhaps he stepped out for a moment or has taken a trip. Perhaps he is sleeping and needs to be awakened."
