Hebrews 2:10-13...and Stuff.

10 For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings.

11 For both he that sanctifieth and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren,

12 Saying, I will declare thy name unto my brethren, in the midst of the church will I sing praise unto thee.

13 And again, I will put my trust in him. And again, Behold I and the children which God hath given me.

KJV

10 In bringing many sons and daughters to glory, it was fitting that God, for whom and through whom everything exists, should make the pioneer of their salvation perfect through what he suffered. 11 Both the one who makes people holy and those who are made holy are of the same family. So Jesus is not ashamed to call them brothers and sisters. 12 He says,

“I will declare your name to my brothers and sisters;
    in the assembly I will sing your praises."

13 And again,

“I will put my trust in him.”

And again he says,

“Here am I, and the children God has given me.”

NIV

10 For it was fitting for Him, for whom are all things, and through whom are all things, in bringing many sons to glory, to perfect the [k]author of their salvation through sufferings. 11 For both He who sanctifies and those who are [l]sanctified are all from one Father; for which reason He is not ashamed to call them brethren, 12 saying,

“I will proclaim Your name to My brethren,
In the midst of the congregation I will sing Your praise.”

13 And again,

“I will put My trust in Him.”

And again,

“Behold, I and the children whom God has given Me.”

NASB

10 For it was an act worthy [of God] and fitting [to the divine nature] that He, for Whose sake and by Whom all things have their existence, in bringing many sons into glory, should make the Pioneer of their salvation perfect [should bring to maturity the human experience necessary to be perfectly equipped for His office as High Priest] through suffering.

11 For both He Who sanctifies [making men holy] and those who are sanctified all have one [Father]. For this reason He is not ashamed to call them brethren;

12 For He says, I will declare Your [the Father’s] name to My brethren; in the midst of the [worshiping] congregation I will sing hymns of praise to You.

13 And again He says, My trust and assured reliance and confident hope shall be fixed in Him. And yet again, Here I am, I and the children whom God has given Me.

AMP (Classic)

...still, just the idea of Him singing. And in our midst, no less. Mind-boggling.

And the idea of being perfectly equipped in His service to God, through suffering?
Hm. Many things.
