I will declare thy name unto my brethren,.... Not those who were more nearly related to him according to the flesh; for though there were some who believed in him, and to whom he declared the name of God, as James and Joses, and Judas and Simon, Mat 13:55; yet there were others that did not believe on him, Joh 7:3; nor those more remotely related to him, as all the Jews, who were his brethren and kinsmen also according to the flesh; to these indeed he came and preached, but they received him not; but rather his apostles, whom he called his brethren, even after his resurrection, and to whom he appeared and declared the name of God, Mat 28:10; and the five hundred brethren by whom he was seen at once may be also included; and even all true believers in him, who through his incarnation, being their "goel" and near kinsman, stands in such a relation to them, and through their adoption into his Father's family, his Father being their Father, and his God their God; which is manifested in regeneration, and evidenced by their doing the will of God, which is believing in Christ, Mat 12:49. By the "name" of God is meant, not anyone of the names by which he is known, as God Almighty, Jehovah, &c. if any of these could be thought to be designed, the New Testament name and title of God as the Father of Christ would bid fair for it; but rather the perfections of God, which appear in Christ, and were glorified in the work of redemption; or God himself; or else his Gospel, Act 9:15; and which Christ declared and manifested to his disciples, both before and after his resurrection, Joh 17:6; which latter seems here to be referred unto; in the midst of the congregation will I praise thee; meaning not the congregation of the Jews, their synagogue, or temple, where he often attended on public worship, and preached and praised the Lord; but rather the company of his disciples, among whom he sung an hymn the night he was betrayed, and with whom he conversed by times for forty days after his resurrection: unless the general assembly and church of the firstborn in heaven is intended, in the midst of which he praised the Lord, when he ascended on high, led captivity captive, and received gifts for men; though it seems best to understand this of the church of God, particularly among the Gentiles, under the Gospel dispensation, where Christ in his members sings the praise of electing, redeeming, and calling grace; see Psa 18:49; compared with Rom 15:9. This is a proof of singing of psalms and hymns in Gospel churches, and of its being a duty to be publicly performed by the members of them, who may expect the presence of Christ in the midst of his church, seeing he here promises to be there: these words are applied to Christ in Heb 2:12.
