John 12:41

41. Saw his glory Saw whose glory? Plainly, according to the passage in the prophet Isaiah 6:1-10, Jehovah’s glory; the term Lord in capitals standing in our Old Testament translation. And this Jehovah is the proper incommunicable name of the God of Israel. And here the Evangelist tells us that this glory of Jehovah was the glory of Jesus of Jehovah-Jesus. He assumes this as being of course the belief of his contemporaneous readers. And this accords with the fact that the earliest Christian Fathers, as Justin Martyr, as well as the biblical scholars of all ages, have held that the Jehovah of the Old Testament, manifesting himself in various ways to the Old Testament saints, was no other than the God manifest in the flesh of the new dispensation.
