Albert Barnes Commentary Matthew 13:7

"And others fell upon the thorns; and the thorns grew up and choked them:" — Matthew 13:7 (ASV)

Among thorns. That is, in a part of the field where the thorns and shrubs had been imperfectly cleared away, and not destroyed. They grew with the grain, crowded it, shaded it, exhausted the earth, and thus choked it.
