Jerusalem as a Useless Vine

1 The word of the LORD came to me:
References for Ezekiel 15:1
      2 “Son of man, how is the wood of a vine different from that of a branch from any of the trees in the forest?
      3 Is wood ever taken from it to make anything useful? Do they make pegs from it to hang things on?
      References for Ezekiel 15:3
      4 And after it is thrown on the fire as fuel and the fire burns both ends and chars the middle, is it then useful for anything?
      References for Ezekiel 15:4
      5 If it was not useful for anything when it was whole, how much less can it be made into something useful when the fire has burned it and it is charred?
