Ambrose of Milan
The true Son of God is none other than the One referenced in the Scripture, ‘You are my Son, today I have begotten you’ (Psalm 2:7).
I will be to him a father, and he shall be to me a son: and I will not take my mercy away from him, as I took it from him that was before thee.
אֲנִי֙ אֶֽהְיֶה־לּ֣וֹ לְאָ֔ב וְה֖וּא יִֽהְיֶה־לִּ֣י לְבֵ֑ן וְחַסְדִּי֙ לֹא־אָסִ֣יר מֵֽעִמּ֔וֹ כַּאֲשֶׁ֣ר הֲסִיר֔וֹתִי מֵאֲשֶׁ֥ר הָיָ֖ה לְפָנֶֽיךָ׃
