Job 2:8 shows Job sitting in ashes scraping himself — a similar posture of extreme grief and humiliation, echoing the ashes here.

Psalm 102:9 also describes eating ashes like bread — a parallel image of deep mourning and affliction, reinforcing the humiliation here.

Proverbs 20:17 warns that deceit leads to a mouth full of gravel — the same image used here to describe suffering. Both link gravel to negative consequence.

Jeremiah 6:26 calls the people to roll in ashes in mourning — the same act of lament described here as imposed by God.

Jonah 3:6 describes the king of Nineveh sitting in ashes as an act of repentance — the same posture of humiliation described here.

Psalm 58:6 uses the same 'break teeth' imagery as a plea for justice against enemies, contrasting with the speaker's own experience here.
