The best texts read ἔδωκεν, gave, the aorist marking Jesus' commission as given once for all.
Was come (ἐξῆλθε)
This rendering would require the perfect tense. The aorist points to His coming as a historic fact, not as related to its result. See on Joh 12:47. Rev., rightly, came forth.
Went (ὑπάγει)
Present tense: goeth; withdrawing from the scenes of earth. Note the original order: that it was from God He came forth, and unto God He is going.
