I will now repeat my earlier arguments in proof of this. When it says: The Lord rained fire from the Lord out of heaven, the word of prophecy declares that there are two in number, One on earth, who, it says, had come down to see the cry of Sodom, and One ever in heaven, who is also Lord of the Lord who is on earth, as being Father and God, and the cause of His being the Mighty One Zephaniah 3:17 and Lord and God.
And again when the word says that God spake in the beginning: Behold Adam has become as one of Us, this phrase as one of Us itself is a declaration of number, and the words do not allow of metaphor, as the sophists endeavour to expound, for they can neither speak the truth nor understand it.
And it is said in [the book of] Wisdom: If I relate to you the things that take place every day, I will remember (also) to tell by number those that are from eternity. The Lord created me as the Beginning of His ways for His works. Before eternity He founded me, in the beginning, before He made the earth, and before He made the depths, and before the springs of waters came forth, before the mountains were founded; and before all hills doth He beget me.
And when I had said all this I continued: You understand, ye who listen to me, if at least you will pay attention, that the word showed that this Offspring has been begotten by the Father before all creatures whatsoever. Now that which is begotten is other in number than that which begets, as every single person will acknowledge.
