By the seed which was sown among the brambles is meant the man who hears the Message, but the cares of life and the glamour of wealth completely choke the Message, so that it gives no return.
Be on your guard lest your minds should ever be dulled by debauches or drunkenness or the anxieties of life, and lest 'That Day' should come suddenly upon you, like a snare.
By that which fell among the brambles are meant those who hear the Message, but who, as they go on their way, are completely choked by this world's cares and wealth and pleasures, and bring nothing to perfection.
Other seed fell into rich soil, and grew, and gave a hundred-fold return." After saying this, Jesus cried aloud: "Let him who has ears to hear with hear."
