Pentakosioi denotes a quantity used for a group of brothers and for a debt amount.

The attested uses mark a quantity in two settings: a group of brothers in 1 Corinthians 15:6 and an amount owed in Luke 7:41.

1. A stated quantity in a group or debt · dominant

   In 1 Corinthians 15:6, the dative plural masculine form occurs with the brothers to whom he appeared; the APB renders the clause “more than five hundred brothers at once.” In Luke 7:41, the accusative plural neuter form occurs in the amount owed by one debtor; the APB renders “the one owed five hundred denarii.”

In the Anselm Project Bible: The APB presents the quantity explicitly in both verses, once for “brothers” and once for “denarii.” These phrases confirm the clauses' quantities rather than isolate a separate English rendering for each form.
