Charles Spurgeon Commentary Hebrews 2:12

"saying, I will declare thy name unto my brethren, In the midst of the congregation will I sing thy praise." — Hebrews 2:12 (ASV)

Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

Here the charge is not to the outside world but to those whom he had called "holy brethren." He drops the word "holy," for there are some so-called brothers who would not deserve that name, and to them he speaks very pointedly: Take heed, take heed, lest there be in any of you an evil heart of unbelief.

And how will that be shown? By wandering off, one way or another, away from the living God.

If your God is not a living God to you—one in whom you live and move and have your being—if he does not come into your daily life, but if your religion is a dead and formal thing, then you will soon depart.

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

Christ, the center of the celestial choirs, is also the center of all the bands of true singers who are still here on earth.

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

That is a quotation from Psalm 22.

Saying, I will declare your name unto my brethren, in the midst of your church will I sing praise unto you.

The apostle was writing to Hebrews, and therefore he quoted from the books with which they were familiar. He here quotes Psalm 22 as the words of the Messiah.
