John Lightfoot on Matthew 13:5

[Some fell among stony places.] Discourse is had concerning some laws of the Kilaim (or, of the seeds of different kinds), and of the seventh year: where, among other things, we meet with these words; "R. Simeon Ben Lachish saith that he is freed [from those laws] who sows his seed by the sea, upon rocks, shelves, and rocky places." These words are spoken according to the reason and nature of the land of Israel, which was very rocky; and yet those places that were so were not altogether unfit for tillage.
