Matthew 3:10

The axe is laid unto the root of the trees. A sign that the tree is to be cut down. The tree meant is the Jewish nation.

Every tree. A fruitless fig-tree was afterward made by our Lord the representative of the whole Jewish nation (Lu 13:6-9), but here John declares a universal law. What does not bear fruit shall finally be destroyed.

Cast into the fire. When the tree is not fruitful, or bears useless fruit, it is fit for nothing but to be burned.
