Luke 6:49

χωρὶς θεμελίου, without a foundation; an important editorial comment. The foolish builder did not make a mistake in choosing a foundation. His folly lay in not thinking of a foundation, but building at haphazard on the surface. Vide notes on Mt. for the characteristics of the two builders. τὸ ῥῆγμα (πτῶσις in Mt.), the collapse, here only in N. T. This noun is used to answer to the verb προσέρρηξεν.

The impression produced by the foregoing study is that Lk's version of the Sermon on the Mount, while faithfully reproducing at least a part of our Lord's teaching on the hill, gives us that teaching, not in its original setting, but readapted so as to serve the practical purposes of Christian instruction, either by Lk. or by some one before him.
