Isaiah 9:18–21
18For wickedness burns like a fire. It devours the briers and thorns; yes, it kindles in the thickets of the forest, and they roll upward in a column of smoke.
19Through Yahweh of Armies’ wrath, the land is burned up; and the people are the fuel for the fire. No one spares his brother.
20One will devour on the right hand, and be hungry; and he will eat on the left hand, and they will not be satisfied. Everyone will eat the flesh of his own arm:
21Manasseh eating Ephraim and Ephraim eating Manasseh, and they together will be against Judah. For all this his anger is not turned away, but his hand is stretched out still.
