12 saying: “I will declare Your name to My brethren; In the midst of the assembly I will sing praise to You.”
Verses 12 and 13 quote Psalm 22:22 and Isaiah 8:13-17. These quotations show that Jesus is not ashamed to call believers His “brethren” (v.11).
Verse 12 quotes Psalm 22:22. It is important to note that Jesus quoted the first verse of this psalm while He was on the cross (Ps 22:1; Mt 27:46). Psalm 22 is a messianic psalm. The author is making these quotes Jesus’ own words. Quotes from Psalm 22 and Isaiah 8 provide scriptural verification of verse 11 (He 2:11).
“I will declare [proclaim] Your name to My brethren;
Jesus can call people who come to Him “brethren.” This is a proclamation of God’s grace. The New Testament applies Psalm 8:14 to Christ (Ro 9:33; 1 Pe 2:8).
In the midst of the assembly I will sing praise to You.”
The “assembly” refers to those who gather in God’s presence, such as the church. This is an indication of Jesus’ presence on earth. The word “assembly” and the word “church” have a common idea—called-out ones.
Jesus will not blush to identify with believers.
Psalm 22 demonstrated the identification of Christ with those He came to save. The Messiah’s message did not come from a distant Mount Olympus: He delivered His message in the midst of the congregation; He took part in humanity. He delivered His message as one of those to whom He spoke.
It is important not to see quotations of Scripture as proof-texts but as texts which bring with them their contexts. Psalm 22 was clearly messianic. The prophetic relevance of this psalm to the crucifixion of Christ is clear in its opening words (Ps 22:1; Mk 15:34; Mt 27:46). Psalm 22:7–8 shows the mockery the Savior endured (Mt 27:39–43). Psalm 22:14–15 describes His anguish on the cross. Psalm 22:16–17 reveals that the Savior’s hands and feet would be “pierced” (Jn 19-31-36). Psalm 22:18 relates that people cast lots for Jesus’ garments (Jn 19:23f; Mt 27:35).
