Isaiah 9:18-21
Unchecked sin spreads like wildfire, producing internal ruin and confirming God’s righteous judgment.
18 For 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.
19 Through Yahweh of Armies’ wrath, the land is burned up; and the people are the fuel for the fire. No one spares his brother.
20 One 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:
21 Manasseh, Ephraim; and Ephraim, Manasseh; and they together shall be against Judah. For all this his anger is not turned away, but his hand is stretched out still.
Unchecked sin spreads like wildfire, producing internal ruin and confirming God’s righteous judgment.
To portray the self-destructive spread of wickedness within Israel and to affirm that internal violence is both consequence and instrument of divine judgment.
During the decline of the northern kingdom, internal conflict, corruption, and instability intensified as the nation moved toward eventual destruction.
