'Rock' in the Bible

Every one therefore that heareth these words of mine, and doeth them, shall be likened unto a wise man, who built his house upon the rock:

and the rain descended, and the floods came, and the winds blew, and beat upon that house; and if fell not: for it was founded upon the rock.

And I also say unto thee, that thou art Peter, and upon this rock I will build my church; and the gates of Hades shall not prevail against it.

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