Luke 3:9

And now also the axe is laid unto the root of the trees,.... Not only to Jesse's family, which as a root in a dry ground, and to Jerusalem, the metropolis of the nation; but to the root of the vain boasting of every Jew; their descent from Abraham, the covenant made with him, their ecclesiastical state and civil polity, all which would quickly be at an end: the Romans were now among them, the axe in God's hand; by means of whom, utter ruin and destruction would be brought upon their nation, city, and temple:

every tree therefore which bringeth not forth good fruit is hewn down, and cast into the fire; Matthew 3:10.
