Theophylact of Ohrid, on Heb 8:10

“For this is the testament which I will make to the house of Israel after those days, saith the Lord: I will give my laws into their mind, and in their heart will I write them: and I will be their God, and they shall be my people:”

“"After those days": which ones? Some say these are the days of the exodus, when the Mosaic law was given. But it seems to me that he is speaking of those days about which he said above: "behold, the days are coming." Thus, after those days have passed, I will establish such a covenant, about which you will hear further. Let the Jew show when he received the unwritten law. For even after the return from Babylon, it was given by Ezra in written form. But the Apostles received nothing in written form; rather, they received the law of the Spirit into their hearts. Therefore Christ also said: "The Comforter... will teach you all things and bring all things to your remembrance" (Cf. Jn. 14:26). This was accomplished through the Gospel. For those who formerly served idols, having now recognized the true God, became His people.”
