or hieratia, denotes "a priest's office," Luke 1:9; Hebrews 7:5, RV, "priest's office" (AV "office of the priesthood").

Notes:
(I) In Romans 11:13, AV, diakonia, "a ministry," is translated "office" (RV, "ministry").
(2) In Acts 1:20, RV, episkope, "an overseership," is translated "office" (marg., "overseership;" AV, "bishopric").
(3) In 1 Timothy 3:1, the word "office," in the phrase "the office of a bishop," has nothing to represent it in the original; the RV marg. gives "overseer" for "bishop," and the phrase lit. is "overseership;" so in 1 Timothy 3:10, 1 Timothy 3:13, where the AV has "use (and 'used') the office of a deacon," the RV rightly omits "office," and translates the verb diakoneo, "to serve," "let them serve as deacons" and "(they that) have served (well) as deacons."
