"Above the mercy seat was the Shekinah, the manifestation of the divine Presence; and from between the cherubim, God made known His will. Divine messages were sometimes communicated to the high priest by a voice from the cloud. Sometimes a light fell upon the angel at the right, to signify approval or acceptance, or a shadow or cloud rested upon the one at the left to reveal disapproval or rejection. PP 349.1"
"And there I will meet with thee, and I will commune with thee from above the mercy seat, from between the two cherubims which are upon the ark of the testimony, of all things which I will give thee in commandment unto the children of Israel."
EGW describes the Shekinah and God's communication from between the cherubim, directly referencing the concept in Exodus 25:22.
"The law of God, enshrined within the ark, was the great rule of righteousness and judgment. That law pronounced death upon the transgressor; but above the law was the mercy seat, upon which the presence of God was revealed, and from which, by virtue of the atonement, pardon was granted to the repentant sinner. Thus in the work of Christ for our redemption, symbolized by the sanctuary service, “mercy and truth are met together; righteousness and peace have kissed each other.” Psalm 85:10 . PP 349.2"
"Mercy and truth are met together; righteousness and peace have kissed each other."
EGW directly quotes Psalm 85:10.
"No language can describe the glory of the scene presented within the sanctuary—the gold-plated walls reflecting the light from the golden candlestick, the brilliant hues of the richly embroidered curtains with their shining angels, the table, and the altar of incense, glittering with gold; beyond the second veil the sacred ark, with its mystic cherubim, and above it the holy Shekinah, the visible manifestation of Jehovah's presence; all but a dim reflection of the glories of the temple of God in heaven, the great center of the work for man's redemption. PP 349.3"
"It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these."
Both passages discuss the earthly sanctuary as a pattern or reflection of the heavenly one.
A period of about half a year was occupied in the building of the tabernacle. When it was completed, Moses examined all the work of the builders, comparing it with the pattern shown him in the mount and the directions he had received from God. “As the Lord had commanded, even so had they done it: and Moses blessed them.” With eager interest the multitudes of Israel crowded around to look upon the sacred structure. While they were contemplating the scene with reverent satisfaction, the pillar of cloud floated over the sanctuary and, descending, enveloped it. “And the glory of the Lord filled the tabernacle.” There was a revealing of the divine majesty, and for a time even Moses could not enter. With deep emotion the people beheld the token that the work of their hands was accepted. There were no loud demonstrations of rejoicing. A solemn awe rested upon all. But the gladness of their hearts welled up in tears of joy, and they murmured low, earnest words of gratitude that God had condesc…
"Then a cloud covered the tent of the congregation, and the glory of the Lord filled the tabernacle."
The EGW passage directly quotes and elaborates on the biblical account of the cloud filling the tabernacle. It's more than a thematic parallel; it's a direct reference.
