Isaías 42

Isaías 42:8

[Eunomius says,] Receiving glory from the Father, not sharing glory with the Father, for the glory of the Almighty is incommunicable, as [the Lord] has said, "I will not give my glory to another." Who is that "other" to whom God has said that he will not give his glory? The prophet is speaking of the adversary of God, yet Eunomius refers the prophecy to the only-begotten God himself! For when the prophet, speaking in the person of God, had said, "I will not give my glory to another," he added, "neither my praise to graven images." — AGAINST EUNOMIUS 2:10
