Cumber the ground (of my vineyard)

1. Jacob 5: 9, 44, 49, 66
   9 Take thou the branches of the wild olive-tree, and graft them in, in the stead thereof; and these which I have plucked off I will cast into the fire and burn them, that they may not cumber the ground of my vineyard.

   44 And thou beheldest that I also cut down that which cumbered this spot of ground, that I might plant this tree in the stead thereof.

   49 And it came to pass that the Lord of the vineyard said unto the servant: Let us go to and hew down the trees of the vineyard and cast them into the fire, that they shall not cumber the ground of my vineyard, for I have done all. What could I have done more for my vineyard?

   66 For it grieveth me that I should lose the trees of my vineyard; wherefore ye shall clear away the bad according as the good shall grow, that the root and the top may be equal in strength, until the good shall overcome the bad, and the bad be hewn down and cast into the fire, that they cumber not the ground of my vineyard; and thus will I sweep away the bad out of my vineyard.
