“‘See!
The day is coming,
Burning
Like an oven.
All the arrogant
Will be stubble.
All evildoers
Will be stubble.
The day that comes
Shall burn them up.’
Says Yahweh of hosts.
Thus,
It will leave them
Neither root
Nor branch.”
The day of Yahweh would be a fiery hot day. The wicked ones would burn up as if they were in an oven. All the arrogant and evildoers would be like stubble for the fire that would burn all of them up. Yahweh of hosts was going to leave these wicked people without roots or branches. Thus, the idea that God will come with fire has its biblical origins here.
