12:41

Isaiah . . . saw his glory: When Isaiah saw a vision of the heavenly courts where Jehovah was sitting on his lofty throne, Jehovah asked Isaiah: “Who will go for us?” (Isa 6:1, 8-10) The use of the plural pronoun “us” indicates that at least one other person was with God in this vision. So it is reasonable to conclude that when John wrote that Isaiah “saw his glory,” this refers to Jesus’ prehuman glory alongside Jehovah. (Joh 1:14) This harmonizes with such scriptures as Ge 1:26, where God said: “Let us make man in our image.” (See also Pr 8:30, 31; Joh 1:1-3; Col 1:15, 16.) John adds that Isaiah spoke about him, that is, the Christ, because a large portion of Isaiah’s writings focuses on the foretold Messiah.
