'Tends' in the Bible

The one who tends a fig tree will eat its fruit, and whoever takes care of his master will be honored.

Like a shepherd he tends his flock; he gathers up the lambs with his arm; he carries them close to his heart; he leads the ewes along.

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?
