In the vision described by Ezekiel, a rainbow-like appearance is noted over the crystal, distinct from the Sea of Glass, composed of spiritual essence rather than physical matter, highlighting the divine nature surrounding God's throne. Ezekiel's account in chapter 1 portrays this rainbow as part of the magnificent and complex imagery of God's glory approaching, emphasizing the spiritual composition of heavenly elements. In Revelation 4, John's vision of God's throne includes a rainbow resembling an emerald, conveying an impression of God's encircling brilliance, mercy, and peace. The emerald's green, brilliant color predominates in this rainbow, symbolizing a profound aspect of God's nature. This rainbow serves as a magnificent emblem of God's mercy and the peace that pervades His Kingdom, underscoring the indescribable splendor of the throne area. Ezekiel further describes the One on the throne with an appearance likened to a rainbow in a cloud on a rainy day, reflecting the glory of the Lord. This vivid imagery captures the transcendent beauty and majesty surrounding God's presence, reinforcing the awe-inspiring nature of the divine scene witnessed in these visions.

In the vision of God's throne, a rainbow appears as a striking element, symbolizing the divine presence and glory. This rainbow, often seen in connection with the cherubim and the temporary, moveable throne of God, accompanies Him wherever He goes. It reflects the eternal quality and splendor of His heavenly domain, contrasting sharply with the chaos and turbulence of the earthly sea. The presence of the rainbow near the throne emphasizes the peace and holiness that define the heavenly realm, standing as a testament to God's sovereign rule and the beauty of His eternal kingdom.

In the vision of God's throne room as described in Revelation 4, an emerald green rainbow arches over the throne, creating a striking image of divine majesty. This circular or semi-circular band of light, referred to as an iris in Greek, enhances the otherworldly splendor surrounding the throne. It contributes to the overwhelming sense of God's fabulous superiority and preeminence, set against a backdrop of stars, galaxies, and a magnificent crystalline sea. The presence of this rainbow adds to the dazzling and beautiful portrayal of God's unapproachable light, emphasizing His incomparable glory and power.
