'Wallow' in the Bible

O daughter of my people [says Jeremiah],Clothe yourself in sackcloth and wallow in ashes;Mourn [aloud] as for an only son,A most bitter cry [of sorrow and regret],For suddenly the destroyer will come upon us [on both prophet and people].

And they will make their voice heard [as they wail loudly] over youAnd they will cry bitterly.They will throw dust on their heads;They will wallow in ashes.

The thing spoken of in the true proverb has happened to them, “The dog returns to his own vomit,” and, “A sow is washed only to wallow [again] in the mire.”
