The seven Spirits of God, Revelation 1:4, Revelation 5:6
One lampstand but seven functions. The Spirit of God, intensified sevenfold to accomplish God's work on earth.
Christ's eyes are the expression of love in Song of Songs but in this prophesy they are like a flame of fire that observes and searches to exercise enlightened judgements. As He first came to set the captives free here He is seen as Him who completes the reading of the scroll set before Him at Luke 4:18
Seven lamps show the enlightenment of the Spirit of God for God's building, Exodus 25:37, Zechariah 4:2 (building and rebuilding of the temple) but the Revelation prophesy reveals the seven lamps of judgment will also issue in God's building; for the building of the New Jerusalem.
Zechariah 3:9
For here is the stone that I have set before Joshua - upon one stone are seven eyes. I will engrave its engraving, declares Jehovah of hosts, and I will remove the iniquity of that land in one day.
Zechariah 4:7
Who are you, O great mountain? Before Zerubbabel you will become a plain, and he will bring forth the top-stone with shouts of Grace, grace to it.
Zechariah 4:10
For who has despised the day of small things? For these seven rejoice when they see the plummet in the hand of Zerubbabel; they are the eyes of Jehovah running to and fro on the whole earth.
The seven Spirits of God are the manifold operations of the one Divine Spirit. The reference as to the Holy Spirit can be considered with respect to his manifold operations, and are regarded as connected with the work of the Redeemer. All the operations of the Spirit are a part of the work of redemption. The expression "sent forth into all the earth," refers to the fact that the Spirit pervades all things. The Spirit of God sent out to survey all things and to operate everywhere.
The seven spirits are also described as being the eyes of the lamb, so the lamb and the light are included in one.
Zachariah 3:9. For this is the stone which I lay before Joshua; there are in the same stone seven eyes: I will engrave it with its engravings, saith the Lord
The seven eyes upon this stone may be seen as the eyes upon the wheels in Ezekiel’s vision, signifying the perfection and plenitude of knowledge and wisdom in Christ Jesus for the good of His church, and His ever watchful care of His people: or the various gifts and graces of the Holy Spirit, with which He was endued: for He hath the seven spirits of God, as well as the seven stars, and His eyes are as a flame of fire, piercing through all disguises, and searching the reins and the heart of every human creature, and especially of every one that professes to be his disciple.
The eye of the Father was upon him, to take care of him and protect him, especially in his sufferings. The eyes of all the prophets and Old Testament saints were upon this one stone: Abraham rejoiced to see Christ’s day, and he saw it and was glad. The eyes of all believers are upon him, as the eyes of the stung Israelites were upon the brazen serpent. They look unto him and are saved.
Christ is not only the rod of the stem of Jesse, the branch that grew out of his roots, the fruit of which is excellent and edifying for the remnant of Israel that escape the corruption which is in the world, but the foundation of the spiritual temple laid in Zion.
Proverbs 24:3-4
Through Wisdom is a house builded; and by Understanding it is established: But by Knowledge shall all the chambers be filled.
Psalms 119:27
Make me to understand the way of thy precepts: so shall I talk of Thy wondrous works.
