Charles Ellicott Commentary Matthew 13:8

"and others fell upon the good ground, and yielded fruit, some a hundredfold, some sixty, some thirty." — Matthew 13:8 (ASV)

Into good ground — Here also the Greek has the definite article, “the good ground.” The different results imply that even here there were different degrees of fertility. The hundredfold return was, perhaps, a somewhat uncommon increase, but the narrative of Isaac’s tillage in Genesis 26:12 shows that it was not unheard of, and had probably helped to make it the standard of a more than usually prosperous harvest.
