'Rock' in the Bible

He is like a man building a house, who digs and goes deep, and lays the foundation on the rock; and when a flood comes, the torrent bursts upon that house, but is unable to shake it, because it is securely built.

Another part drops upon the rock, and after growing up it withers away for want of moisture.

Those on the rock are the people who on hearing the Message receive it joyfully; but they have no root: for a time they believe, but when trial comes they fall away.

Then, taking it down, he wrapped it in a linen sheet and laid it in a tomb in the rock, where no one else had yet been put.
