Speaking to Manoah and his wife, he told them they couldn't understand his name [Judges 13:18].
He has a name on his head that only he comprehends when he appears as the 5th horseman and seventh seal [Revelation 19:11-16].
7 eyed stone with a mysterious name inscribed [Zechariah 3:6-9].
I think it's a variant of Elohim, his nature as various manifestations of the formless infinity that animates the world. Even if he directly explained it to us we'd need to see it directly.... he does give us a lot to read.
