<3,,4218, pote>
denotes "once upon a time, formerly, sometime," e.g., Rom 7:9, Gal 1:1, 1-st part, RV, "once" (AV, "in times past"); 2nd part, AV and RV, "once;" Gal 2:6, RV marg., "what they once were" (to be preferred to the text, "whatsoever they were"), the reference probably being to the association of the twelve Apostles with the Lord during His ministry on earth; upon this their partisans based their claim for the exclusive authority of these Apostles, which Paul vigorously repudiated; in Eph 5:8, RV, "once" (AV, "sometimes"). See AFORETIME, LAST, LENGTH (at), TIME (past).
Note: In Luk 23:18, AV, pamplethei, denoting "with the whole multitude" (pas, "all," plethos, "a multitude"), is rendered "all at once," RV, "all together").
