1 Corinthians 3:6-8

3:6 I planted, Apollos watered, but God caused it to grow. 3:7 So neither the one who plants counts for anything, nor the one who waters, but God who causes the growth. 3:8 The one who plants and the one who waters work as one, but each will receive his reward according to his work.

1 Corinthians 9:7

9:7 Who ever serves in the army at his own expense? Who plants a vineyard and does not eat its fruit? Who tends a flock and does not consume its milk?
