Hebrews 2:10 "...bring many sons to glory..."?

[Stope]

"For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering."
Hebrews 2:10

I had 2 questions:
1. What is meant by the fact that Jesus will bring many sons to "glory"? What is the nature of this glory?
2. How does it follow that it was "fitting" that "He" (is this God?) should make Jesus/creator/sustainer/founder of salvation "perfect through suffering"?

 

[Contra_Mundum]

Is. 53:10 says of Messiah, "He shall see his seed." The object is usually offspring of some kind. However, there are no physical sons of Jesus; therefore these must be his heritage of the spirit. This is consistent with many other expressions from Isaiah, such as 49:22 or 9:6. The "glory" is true glory, everlasting glory, the presence of God. It is that glory of God that sinners fall short of, which originates with God and which his saints reflect back upon him.

The fitness or corresponding appropriateness of his suffering, is explained by the following verse 11, together with previous statements such as in v9 expressing the reality that sinners suffer already and are due to suffer the worst of woe apart from a Savior's help. His sufferings suit their just desserts; and by enduring them he is thereby designated as his "children's" Mediator in whom they are all one. And he is not ashamed to call them brethren.
