Hebrews 13:20

θεὸς τῆς εἰρήνης. The phrase is frequent in St Paul (1 Thessalonians 5:23; 2 Thessalonians 3:16; Romans 15:33; Romans 16:20; Philippians 4:9).

ὁ�. Among many allusions to the Ascension and Glorification of Christ this is the only direct allusion in the Epistle to His Resurrection (but comp. Hebrews 6:2; Hebrews 11:35). The verb ἀνήγαγεν may be “raised again” rather than “brought up,” though there may be a reminiscence of “the shepherd” (Moses) who “brought up” his people from the sea in Isaiah 63:11.

ἐν αἵματι κ.τ.λ. “By virtue of (lit. “in”) the blood of an eternal covenant.” The expression finds its full explanation in Hebrews 9:15-18. Others connect it with “the Great Shepherd.” He became the Great Shepherd by means of His blood. So in Acts 20:28 we have “to shepherd the Church of God, which He purchased for Himself by means of His own blood.” A similar phrase occurs in Zechariah 9:11, “By (or “because of”) the blood of thy covenant I have sent forth thy prisoners out of the pit.”
