He is like a man who built a house and dug deep and laid the foundation on a rock; and a flood occurring, the stream burst against that house and could not shake it; for it was founded on a rock.

And other fell on a rock, and sprouting, it withered away, because it lacked moisture.

Those on the rock are the ones who, when they hear, receive the Word with joy. And these have no root, who for a while believe, and in time of temptation fall away.
