John Gill

Verily, I say unto thee,.... This may be depended upon, you may assure yourself of it, that thou shalt by no means come out thence, from prison, till thou hast paid the uttermost farthing, or "last farthing"; or as the Ethiopic version reads it, "till thou hast exactly paid all"; which seems to express the inexorableness of the creditor, and the impossibility of the debtor's release.
