The God of peace (o qeo th eirhnh). God is the author and giver of peace, a Pauline phrase (6 times) as in 1 Thessalonians 5:23 . Who brought again from the dead (o anagagwn ek nekrwn). Second aorist active articular participle of anagw (cf. Romans 10:7 ), the only direct mention of the resurrection of Jesus in the Epistle, though implied often ( Hebrews 1:3 , etc.). That great shepherd of the sheep (ton poimena twn probatwn ton megan). This phrase occurs in Isaiah 63:11 except ton megan which the author adds as in Hebrews 4:14 ; Hebrews 10:21 . So here, "the shepherd of the sheep the great one." With the blood of the eternal covenant (en aimati diaqhkh aiwniou). This language is from Zechariah 9:11 . The language reminds us of Christ's own words in Mark 14:24 ( Matthew 26:28 ; Luke 22:20 ; 1 Corinthians 11:25 ) about "my blood of the covenant."
