'Rock' in the Bible

"Every one who hears these my teachings and acts upon them will be found to resemble a wise man who builds his house upon rock;

and the heavy rain falls, the swollen torrents come, and the winds blow and beat against the house; yet it does not fall, for its foundation is on rock.

And I declare to you that you are Peter, and that upon this Rock I will build my Church, and the might of Hades shall not triumph over it.

He then laid it in his own new tomb which he had hewn in the solid rock, and after rolling a great stone against the door of the tomb he went home.
