'Rock' in the Bible

"Everyone therefore who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock.

The rain came down, the floods came, and the winds blew, and beat on that house; and it didn't fall, for it was founded on the rock.

I also tell you that you are Peter, and on this rock I will build my assembly, and the gates of Hades will not prevail against it.

and laid it in his own new tomb, which he had cut out in the rock, and he rolled a great stone to the door of the tomb, and departed.
