'Plants' in the Bible

So neither the one who plants nor the one who waters is significant, but God, who keeps everything growing, is the one who matters.

The one who plants and the one who waters have the same goal, and each will receive a reward for his own action.

Who ever goes to war at his own expense? Who plants a vineyard and does not eat any of its grapes? Or who takes care of a flock and does not drink any of its milk?
