I went up by revelation (2:1–2)

Says Galatians 2:1 opens Ἔπειτα διὰ δεκατεσσάρων ἐτῶν (Epeita dia dekatessarōn etōn, “then after fourteen years”): διά with the genitive marks the interval, which the BSB gives as “Fourteen years later”. The verb is πάλιν ἀνέβην (palin anebēn, “I went up again”), μετὰ Βαρναβᾶ, and the participle συμπαραλαβὼν καὶ Τίτον adds that Titus was taken along.

Says Galatians 2:2 repeats the verb and gives its ground, κατὰ ἀποκάλυψιν (kata apokalypsin, “in accordance with a revelation”). Paul ἀνεθέμην αὐτοῖς (anethemēn autois, “set before them”) the gospel he preaches; Abbott-Smith gives the middle as “to set forth, declare” at this verse. He did so κατ’ ἰδίαν δὲ τοῖς δοκοῦσιν; for οἱ δοκοῦντες here Abbott-Smith has “those of repute” (BSB “those recognized as leaders”). The clause μή πως εἰς κενὸν τρέχω ἢ ἔδραμον (mē pōs eis kenon trechō ē edramon) uses εἰς κενόν, “in vain, to no purpose”, with τρέχω listed under “Metaph., from runners in a race, of swiftness or of effort to attain an end”.

Implies The visit is framed by revelation, not summons, which keeps the point of 1:11–12: Paul’s gospel came by revelation, and he lays it before the leaders without receiving it from them.

Uncertain The Greek does not say which visit in Acts this is, or from what point the fourteen years are counted. No lean is taken here.
