His own glory (τὴν δοÌξαν τὴν ἰδιÌαν)
Literally, the glow which is His own; the second article throwing His own into sharp contrast with His that sent Him. On His own, see on Act 1:7; see on Mat 22:5; see on Mat 25:15.
The same (οὖτος)
Notice the characteristic use of the pronoun taking up and emphasizing the principal subject of the sentence.
