John 12:41

“These things said Esaias, etc.] Concerning the blinding and hardening of the Jews: when he saw his glory, and spake of him; when he saw, in a visionary way, the glory of the Messiah in the temple, and the angels covering their faces with their wings at the sight of him; and when he spake of him as the King, the Lord of hosts, whom he had seen, (<230601>Isaiah 6:1-10), from whence it is clear that he had respect to the Jews in the times of the Messiah. The prophet says in (<230601>Isaiah 6:1) that he “saw the Lord”: the Targumist renders it, “I saw”, yyd arqy ta, “the glory of Jehovah”; and in (<230605>Isaiah 6:5) he says, “mine eyes have seen the King”, Jehovah, Zebaot, the Lord of hosts;…”

“These things said Esaias, when he saw his glory, and spake of him--a key of immense importance to the opening of Isaiah's vision (Isa 6:1-13), and all similar Old Testament representations.

“When he saw his glory - Isaiah 6:1-10. Isaiah saw the Lord (in Hebrew, יהוה Yahweh) sitting on a throne and surrounded with the seraphim. This is perhaps the only instance in the Bible in which Yahweh is said to have been seen by man, and for this the Jews affirm that Isaiah was put to death. God had said Exodus 33:20, “No man shall see me and live;” and as Isaiah affirmed that he had seen Yahweh, the Jews, for that and other reasons, put him to death by sawing him asunder. See Introduction to Isaiah, Section 2. In the prophecy Isaiah is said expressly to have seen Yahweh John 12:1; and in John 12:5, “Mine eyes have seen the King Yahweh of hosts.” By his glory is meant the manifestation of…”

“When he saw his glory - Christ's, Isa 6:1, &c. And it is there expressly said to be the glory of the Lord, Jehovah, the Supreme God. John 12:44”

“12:41 Isaiah had glimpsed the Messiah’s glory and how the world would respond (see Isa 6:10).”

“when: Isa 6:1-5, Isa 6:9, Isa 6:10 saw: Joh 1:14, Joh 1:18, Joh 14:9; Exo 33:18-23; Co2 4:6; Heb 1:3 spake: Joh 5:39; Act 10:43; Pe1 1:11; Rev 19:10 John 12:42”
