"themselves: "Give back (apodidomi) to Caesar the property that belongs to Caesar ..." The verb apodidomi, often translated as "render unto," is actually a compound word: apo is a preposition that in this case means "back again"; didomi is a verb meaning "to give." Apodidomi is used specifically when paying someone back property to which he is entitled; the word implies that the person receiving payment is the rightful owner of the thing being paid."
