2 Corinthians 9:10 Now he that ministereth seed to the sower both minister bread for your food, and multiply your seed sown, and increase the fruits of your righteousness;)

The Apostle Paul cited the words of the Isaiah in Isaiah 55:10 For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater: God is the subject of this verse. He is the Nourisher and Supplier of the rain and the snow from heaven to bring forth the harvest that gives the bread on our table for each meal.

Another verse alluded to is Hosea 10:12 Sow to yourselves in righteousness, reap in mercy; break up your fallow ground: for it is time to seek the LORD, till he come and rain righteousness upon you.
