Cross-reference
Jeremiah 2:30 laments that God's striking brought no correction—the exact frustration implied in the condition 'if you do not accept my correction'.
In Jeremiah 5:3, God strikes but they refuse correction—mirroring the stubborn resistance that triggers sevenfold punishment here.
Amos 4:6-12 lists escalating judgments with the refrain 'yet you did not return'—a direct parallel to the sevenfold strikes here for unrepentant opposition.
Psalm 18:26 says God shows himself twisted to the crooked — the same reciprocal logic as God walking contrary to those who walk contrary.
Isaiah 1:16-20 offers cleansing and blessing if repentant, but warns of the sword if rebellious—the same conditional logic as the discipline here.
Ezekiel 24:13 describes God's purging rejected, leading to unrestrained fury—similar to the intensified judgment for refusing to listen here.
2 Samuel 22:27 says God shows Himself twisted to the crooked—a parallel principle: hostile response to the hostile, echoing the sevenfold strikes here.
