'Rock' in the Bible

Other seed fell on rock, and when it came up, it withered because it had no moisture.

Those on the rock are the ones who receive the word with joy when they hear it, but they have no root. They believe for a while, but in a time of testing fall away.

Then he took it down, wrapped it in a linen cloth, and placed it in a tomb cut out of the rock, where no one had yet been buried.
