Charles Spurgeon Commentary Matthew 13:5

"and others fell upon the rocky places, where they had not much earth: and straightway they sprang up, because they had no deepness of earth:" — Matthew 13:5 (ASV)

Some fell upon stony places, where they had not much earth:

There was a pan of unbroken limestone an inch or two below the soil, but there was no depth of earth where the seeds could grow.

And forthwith they sprung up, because they had no deepness of earth:

They seemed to be converts, but they proved to be worthless.

They were enthusiastic, carried away with excitement, but all was soon over with them because they had no deepness of earth.

Everything was superficial, there was no depth of character, or feeling, or emotion.
