sek´un - da - ri - 51 : the King James Version for ( δεύτερον , deúteron ) ( 1 Corinthians 12:28 ). Probably without distinction from "secondly" (so the Revised Version (British and American), and so the King James Version also for deuteron in Sirach 23:23). Still the King James Version may have wished to emphasize that the prophets have a lower rank than the apostles.
