'Stream' in the Bible

He is like a man building a house, who dug and went deep, and laid a foundation on the rock; but a great rain coming, the stream broke upon that house, and could not shake it, for it had been founded on the rock.

And he that has heard and not done, is like a man who has built a house on the ground without a foundation, on which the stream broke, and immediately it fell, and the breach of that house was great.
