2:12 {13} Saying, I will declare thy name unto my brethren, in the midst of the church will I sing praise unto thee.
(13) That which he taught before about the incarnation of Christ, he applies to the prophetic office.
2:12 In the midst of the church. Congregation is the term used in Ps 22:22. The Revised Version has so rendered it here.
2:12 I will declare thy name to my brethren - Christ declares the name of God, gracious and merciful, plenteous in goodness and truth, to all who believe, that they also may praise him. In the midst of the church will I sing praise unto thee - As the precentor of the choir. This he did literally, in the midst of his apostles, on the night before his passion. And as it means, in a more general sense, setting forth the praise of God, he has done it in the church by his word and his Spirit; he still does, and will do it throughout all generations. Psa 22:22.
2:10-13 Whatever the proud, carnal, and unbelieving may imagine or object, the spiritual mind will see peculiar glory in the cross of Christ, and be satisfied that it became Him, who in all things displays his own perfections in bringing many sons to glory, to make the Author of their salvation perfect through sufferings. His way to the crown was by the cross, and so must that of his people be. Christ sanctifies; he has purchased and sent the sanctifying Spirit: the Spirit sanctifies as the Spirit of Christ. True believers are sanctified, endowed with holy principles and powers, set apart to high and holy uses and purposes. Christ and believers are all of one heavenly Father, who is God. They are brought into relation with Christ. But the words, his not being ashamed to call them brethren, express the high superiority of Christ to the human nature. This is shown from three texts of Scripture. See Ps 22:22; 18:2; Isa 8:18.
