Explainer / Messiah
Romans 9:5
whose are the fathers, and of whom is Messiah as concerning the flesh. God who is over all be blessed forever. Amen.
ὧν οἱ πατέρες, καὶ ἐξ ὧν ὁ χριστὸς τὸ κατὰ σάρκα, ὁ ὢν ἐπὶ πάντων, θεὸς εὐλογητὸς εἰς τοὺς αἰῶνας· ἀμήν.
Compare with the ASV
whose are the fathers, and of whom is Christ as concerning the flesh, who is over all, God blessed for ever. Amen.
We put a full stop after "flesh" and printed the last line as a blessing of God: "God who is over all be blessed forever. Amen."
Why
The manuscripts have no punctuation
The early Greek manuscripts were written without punctuation marks, so where a sentence stops is an editor's choice, not part of the text.
The words of a blessing
εὐλογητὸς εἰς τοὺς αἰῶνας, "blessed forever," is the wording Paul uses when he blesses God (Rom 1:25, ὅς ἐστιν εὐλογητὸς εἰς τοὺς αἰῶνας· ἀμήν; 2 Cor 11:31, ὁ ὢν εὐλογητὸς εἰς τοὺς αἰῶνας).
More
With a full stop after "flesh," the line is a blessing of that kind, ending with "Amen" as in Rom 1:25.
"Be blessed."
The Greek has no verb.
More
English supplies one. With the full stop, "be blessed" makes the line a blessing rather than a statement.
"God who is over all be blessed for ever" (ASV margin, RSV, NEB, REB); "Christ, who is God over all, blessed forever" (ESV, NIV, NASB); "Christ … who is over all, God blessed for ever" (ASV text).
