'River' in the Bible

he is like a man building a house, who dug and went down deep and laid the foundation on the rock. And [when] a flood came, the river burst against that house and was not able to shake it, because it had been built well.

But the one who hears [my words] and does not do [them] is like a man who built a house on the ground without a foundation, which the river burst against, and immediately it collapsed--and the collapse of that house was great!"
