A.T. Robertson Commentary Matthew 18:23

"Therefore is the kingdom of heaven likened unto a certain king, who would make a reckoning with his servants." — Matthew 18:23 (ASV)

Make a reckoning (συναρα λογον). Seen also in 25:19. Perhaps a Latinism, rationes

conferre. First aorist active infinitive of συναιρω, to cast up accounts, to settle, to compare accounts with. Not in ancient Greek writers, but in two papyri of the second century A.D. in the very sense here and the substantive appears in an ostracon from Nubia of the early third century (Deissmann, Light from the Ancient East, p. 117).
