You should Look at Proverbs VIII : 22-31:
Verse 22. “The Lord possessed me in the beginning of his ways, before he made any thing from the beginning.”
23. “I was set up from eternity and of old, before the earth was made.”
24. “The depths were not as yet and I was already conceived: neither had the fountains of waters as yet sprung out.”
25. “The mountains with their huge bulk had not as yet been established: before the hills I was brought forth.”
26. “He had not yet made the earth, nor the rivers, nor the poles of the earth.”
27. “When he prepared the heavens, I was present: when with a certain law and compass he enclosed the depths.”
28. “When he established the sky above and poised the fountains of waters.”
29. “When he compassed the sea with its bounds, and set a law to the waters that they should not pass their limits: when be balanced the foundations of the earth.”
30. “I was with Him forming all things: and was delighted every day, playing before Him at all times.”
31. “Playing in the world: and my delights were to be with the children of men.”
The Literal sense of this would be :
That it treats of the ideas or decrees, which were in the Divine Mind before the Creation of the world; and that, in its literal sense, it speaks of the Person of the Incarnate Word and of his most holy Mother, while in its mystical sense it refers to the holy angels and prophets. For before decreeing or forming the ideals of the rest of the material creation, He formed and decreed their prototype, the most sacred humanity of Christ and of his purest Mother, and this is indicated by the first words.
And the Mystical Sense would be:
“The Lord possessed me in the beginning of his ways.” In God there are no ways, and his Divinity does not need them: but He made use of them, in order, that by them we may know Him and that all of us creatures, who are capable of knowing Him, may tend toward Him. In this beginning, before He formed any other ideal in his mind, because He desired to create paths and open ways in his mind for the communication of the Divinity, He decreed, as a beginning, the formation of the humanity of the Word, who was to be the highway, by which the other creatures might come to the Father (Joan. 14, 6). Joined with this decree was that of his most holy Mother, through whom his Divinity was to enter into the world, becoming man and being born from Her as God and man; therefore it is said: “God possessed me” since both were possessed by his Majesty: for as to his Divinity, He was the possession, the property, and the treasure of the Father without possibility of separation, because Father and Son are One, of the same substance and Divinity with the Holy Ghost; and also as to his humanity, the Father possessed the Son; because He himself knew and decreed the plenitude of grace and glory, which He was to bestow upon it at the moment of its creation and its hypostatical union. Moreover, as this decree and possession was to be brought about by the mediation of the Mother, who was to conceive and bring forth the Word (since He did not decide to create it out of nothing, nor form his soul and body out of any other material), it followed that He possessed Her, who was to give Him the human form. Thus He possessed and claimed Her as his own in the same instant, providing with solicitude, that in the order of grace neither the human race nor any other, should have at any time a right or a part in Her. He alone retained the full right in Her as his portion, and so much his portion as the dignity of Mother required. She alone was to call Him Son, and She alone was to be called Mother, a Mother worthy of having an incarnate God for a Son. Now as all this far surpassed in dignity the whole creation, so did it also take the precedence in the mind of the supreme Creator. Hence He says:
“Before He made anything from the beginning, I was set up from eternity and of old.” We, in our present state, conceive this eternity of God as an interminable time. What were the things “of old,” since none had been created? It is clear that the three Persons are here spoken of, namely, that She was foreseen from the eternal ages of the Divinity, by the Beings, which alone are ancient, namely, the indivisible Trinity (since all the rest, having a beginning, are recent), that She was foreseen when only the ancient Uncreated was, and before any ideals of the future creation were formed. Between these two extremes intervened the ideal of the hypostatic union which was to be verified
ad extra through the intervention of the most holy Mary. Both were ordained together, immediately next to God and before any other creature, and it was the most wonderful decree ever passed or ever to be passed. The first and most admirable image in the mind of God, next to the eternal generation, was that of Christ and next to it, that of his Mother.

I will stop there. That basically explains the first two versus thoroughly, and also show God as Triune; Father, Son, and Holy Ghost.
