And the rain fell, and the floods came, and the winds blew and slammed against that house; and yet it did not fall, for it had been founded on the rock.

I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it.

and laid it in his own new tomb, which he had hewn out in the rock; and he rolled a large stone against the entrance of the tomb and went away.
