'Rock' in the Bible

He is like a man building a house, who went deep and put the base of it on a rock; and when the water came up and the river was driving against that house, it was not moved, because the building was good.

And some went on the rock, and when it came up it became dry and dead because it had no water.

And those on the rock are those who with joy give hearing to the word; but having no root, they have faith for a time, and when the test comes they give up.

And he took it down, and folding it in a linen cloth, he put it in a place cut in the rock for a dead body; and no one had ever been put in it.
