John Trapp on Hebrews 6:7

Verſe 7. And bringeth forth herbs] So the fruitfull Chriſtian (that watered with the Word and Spirit, bringeth forth a harveſt of holineſſe) ſhall receive the bleſſing of encreaſe, Iob. 1.2. Such trees as brought forth fruit fit for meat, were not to be deſtroied, Dout. 20.19. But trees that were not for fruit, were for the fire, Mat. 3.10.
