The fruits of your labor

An unproduced a harvest.

Some fell upon stony places, where they had not much earth: and forthwith they sprung up, because they had no deepness of earth: Matthew 13:5 KJV

And When the sun was up, they were scorched; and because they had no root, they withered away. Matthew 13:6 KJV

As for what was sown on thin (rocky) soil, this is he who hears the Word and at once welcomes and accepts it with joy; Matthew 13:20 AMP
