'Rock' in the Bible

The deep covered them, they went down into the depths like a rock.

I'll be standing there in front of you on the rock at Horeb. You are to strike the rock and water will come out of it, so the people can drink." Moses did this in front of the elders of Israel.

"If people quarrel and one strikes the other with a rock or his fist, and he does not die but ends up in bed,

The LORD said, "Look, there is a place near me where you can stand on the rock;

and as my glory passes by, I'll put you in a crevice in the rock, and cover you with my hand until I've passed by.
