NET

49 But the person who hears and does not put my words into practice is like a man who built a house on the ground without a foundation. When the river burst against that house, it collapsed immediately, and was utterly destroyed!”

Darby

49 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.

KJV

49 “But he that heareth, and doeth not, is like a man that without a foundation built an house upon the earth; against which the stream did beat vehemently, and immediately it fell; and the ruin of that house was great.”
