The Bible, from Genesis to Revelation, is all one book, inspired by God, over a period of 1500 years. The O.T. does give us a hint of the N.T. further revelation of the Trinitarian nature of The ONE God. That ONE God in three Persons says in Genesis.. "Let US make man in OUR image and in OUR likeness.." (Gen.1:26) The O.T. shows that over and over again we FINITE little human beings offend our INFINITE God with sin. So we incurred a debt that we can not repay! A finite being can not repay an infinite debt! So, as the scripture says. "God put on flesh.." so that He could come down and pay the terrible Price that we owed for our sins. Our sins nailed Him there! And there are MANY Genre's in the bible not just the spiritual Genre. There is the Figurative and there is the Literal.. the Narrative.. Poetic.. Prophetic.. Historic.. Apocalyptic.. and Spiritual.. to name just a few. "In the beginning God created.." a physical world, not a spiritual world. Archeology has confirmed the historical accuracy of many of the names, places. and events described in the Old and New Testaments. In John 6 many of Jesus' disciples walked away from Him muttering.."How can this man (man?) give us His flesh to eat?" "..And they walked away and no longer went about with Him." (Jn.6:66) Jesus could have easily called them back by saying "Oh I only meant that spiritually." But instead.. Jesus let them walk.
Are you aware there are ((7)) different Divine Councils we can find throughout the Tanakh (Old Testament)? Psalms 82 is one of the easiest ones to copy/paste:
1 A song of Asaph. God stands in the congregation of God; in the midst of the judges He will judge.
אמִזְמ֗וֹר לְאָ֫סָ֥ף אֱלֹהִ֗ים נִצָּ֥ב בַּֽעֲדַת־אֵ֑ל בְּקֶ֖רֶב אֱלֹהִ֣ים יִשְׁפֹּֽט:
2 How long will you judge unjustly and favor the wicked forever?
בעַד־מָתַ֣י תִּשְׁפְּטוּ־עָ֑וֶל וּפְנֵ֥י רְ֜שָׁעִ֗ים תִּשְׂאוּ־סֶֽלָה:
3 Judge the poor and orphan; justify the humble and the impoverished.
גשִׁפְטוּ־דָ֥ל וְיָת֑וֹם עָנִ֖י וָרָ֣שׁ הַצְדִּֽיקוּ:
4 Release the poor and the needy; save [them] from the hands of [the] wicked.
דפַּלְּטוּ־דַ֣ל וְאֶבְי֑וֹן מִיַּ֖ד רְשָׁעִ֣ים הַצִּֽילוּ:
5 They did not know and they do not understand [that] they will walk in darkness; all the foundations of the earth will totter.
הלֹ֚א יָֽדְע֨וּ | וְלֹ֬א יָבִ֗ינוּ בַּֽחֲשֵׁכָ֥ה יִתְהַלָּ֑כוּ יִ֜מּ֗וֹטוּ כָּל־מ֥וֹסְדֵי אָֽרֶץ:
6 I said, "You are angelic creatures, and all of you are angels of the Most High."
ואֲֽנִ֣י אָ֖מַרְתִּי אֱלֹהִ֣ים אַתֶּ֑ם וּבְנֵ֖י עֶלְי֣וֹן כֻּלְּכֶֽם:
7 Indeed, as man, you will die, and as one of the princes, you will fall.
זאָכֵ֥ן כְּאָדָ֣ם תְּמוּת֑וּן וּכְאַחַ֖ד הַשָּׂרִ֣ים תִּפֹּֽלוּ:
8 Arise, O God, judge the earth, for You inherit all the nations.
חקוּמָ֣ה אֱ֖לֹהִים שָׁפְטָ֣ה הָאָ֑רֶץ כִּֽי־אַתָּ֥ה תִ֜נְחַ֗ל בְּכָל־הַגּוֹיִֽם:

Knowing there are Councils that God Himself has designed and set-up, how do you know that God was not in one of His Councils in Genesis 1:26?
