The first article of the seven Spirits of God is the Spirit of Wisdom. In Hebrew it is CHOKMAH.
Proverb 8:12 I wisdom...8:22-23 YHWH possessed me, The beginning of His way, As the first of His works of old, I was set up ages ago, at the first,...
Psalms 111:10 The fear of YHWH is the beginning of wisdom: a good understanding have all they that do His commandments:

And the church of Ephesus is the first church in Revelations and the name Ephesus means “permitted”. Which has to do with the first feast Pesach. The season of our freedom from slavery. The death angel was permitted to kill all the first born in Egypt, but was not permitted to kill any of the Israelites. None of the Israelites were permitted to go out of their house until morning.

An interesting fact is that Ephesus from 100 BC to 100 c AD was the slave trade capital of the world.

Ephesus was told to “repent and do the deeds you did at first, or else I am coming to you and will remove your lampstand out of its place”.

Jeremiah 2:2 “Go and proclaim in the ears of Jerusalem, saying, 'thus says YHWH, “I remember concerning you the devotion of your youth, The love of your betrothals, Your following after Me in the wilderness, Through a land not sown.

It also has to do with the first fruits determining the first month. The first fruits are holy and for YHWH.

The Rome Church was very unwise in its attempt to rid the world of the Passover of YHWH in devouring this holy fruit. And stopping YHWH's people from keeping this perpetual feast.

“Constantine's Creed: ...A Jew 'Must confess and denounce verbally, the whole of Hebrew people, forthwith declare that with a whole heart and sincere faith he desires to be received among the Christians. Then he must renounce all customs, rites, legalisms, unleavened breads and sacrifices of the lambs of the Hebrews, all of the other feasts of the Hebrews, sacrifices, prayers, aspersions, new moons, and Sabbaths, and superstitions, and hymns and chants, and observances of the synagogues, and the food and drink of the Hebrews; (Stefano Assemani, Acta Sanctorium Maryrum Orientalium at Occidentalium, Vol. 1, Rome 1748, page 105).

The Wisdom Spirit is also associated with light in Ecclesiastes 2:13 “And I saw that wisdom excels folly as light excels darkness”.
