Ezekiel 15:2
15:2 Son of man, What is the vine tree more than any tree, [or
     than] a branch which is among the {a} trees of the forest?

     (a) Which brings forth no fruit, no more than the other
         trees of the forest do: meaning that if Jerusalem,
         which bore the name of his Church, did not bring forth
         fruit it would be utterly destroyed.

Ezekiel 15:7
15:7 And I will set my face against them; they shall go out from
     [one] {b} fire, and [another] fire shall devour them; and
     ye shall know that I [am] the LORD, when I set my face
     against them.

     (b) Though they escape one danger, yet another will take
         them.
