“Do you need me to layout the problem?”
There is no problem. Luke says he was waiting “for the consolation of Israel” (Isa. 40:1) and the Holy Spirit designated him as a “measuring” life for the coming of Immanuel. For him to understand who the “consolation” and “light” was he first had to know the scriptures (Isa. 9:2).
I have no problem.
You, on the other hand, have to find the Old Testament verse explaining Lk 2:29 to maintain your man-made doctrine defining "The Word of God."
