'Stock' in the Bible

I planted you in the land like a special vine of the very best stock. Why in the world have you turned into something like a wild vine that produces rotten, foul-smelling grapes?

Saying to a stock, Thou art my father; and to a stone, Thou hast brought me forth: for they have turned their back unto me, and not their face: but in the time of their trouble they will say, Arise, and save us.

But they are altogether brutish and foolish: the stock is a doctrine of vanities.
