And some fell among thorns,.... The word was ministered to some who were eat up with the cares of the world, and the deceitfulness of riches, and other lusts:
and the thorns grew up, and choked it; the word did not take place so as to beat down, overcome, and root out these things, nor even to weaken, and keep under, and prevent the influence of them; but these got the ascendant of the word, and prevailed over it, and made it altogether useless and unsuccessful: for whilst it was administered, the minds of these persons were after their riches and worldly things, and gave no heed to the word; and last were prevailed upon, not to attend upon it, but drop the profession of it:
and it yielded no fruit; it was not the means of grace; faith did not come by it, nor any other grace; nor did it produce good works in the life and conversation.

And some fell among thorns, and the thorns grew up, and choked it, and it yielded no fruit--This case is that of ground not thoroughly cleaned of the thistles, &c.; which, rising above the good seed, "choke" or "smother" it, excluding light and air, and drawing away the moisture and richness of the soil. Hence it "becomes unfruitful" (Matthew 13:22); it grows, but its growth is checked, and it never ripens. The evil here is neither a hard nor a shallow soil--there is softness enough, and depth enough; but it is the existence in it of what draws all the moisture and richness of the soil away to itself, and so starves the plant. What now are these "thorns?" See on Mark 4:19.
Fourth Case: THE GOOD GROUND. (Mark 4:8, Mark 4:20).
