"And I saw another field full of all kinds of flowers, and as I plucked them, I cried out: “They will never fade.” Next I saw a field of tall grass, most glorious to behold; it was living green, and had a reflection of silver and gold, as it waved proudly to the glory of King Jesus. Then we entered a field full of all kinds of beasts—the lion, the lamb, the leopard, and the wolf, all together in perfect union. We passed through the midst of them, and they followed on peaceably after. Then we entered a wood, not like the dark woods we have here; no, no; but light, and all over glorious; the branches of the trees waved to and fro, and we all cried out: “We will dwell safely in the wilderness and sleep in the woods.” We passed through the woods, for we were on our way to Mount Zion. 1T 68.1"
"The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them."
The EGW passage directly references the imagery of animals dwelling together peacefully, which is a clear and explicit allusion to Isaiah 11:6. The specific animals mentioned (wolf, lamb, leopard) further solidify this connection.
"red as a border on their garments; their crowns were brilliant; their robes were pure white. As we greeted them, I asked Jesus who they were. He said they were martyrs that had been slain for Him. With them was an innumerable company of little ones; they had a hem of red on their garments also. Mount Zion was just before us, and on the mount was a glorious temple, and about it were seven other mountains, on which grew roses and lilies. And I saw the little ones climb, or, if they chose, use their little wings and fly to the top of the mountains, and pluck the never-fading flowers. There were all kinds of trees around the temple to beautify the place—the box, the pine, the fir, the oil, the myrtle, the pomegranate, and the fig tree bowed down with the weight of its timely figs; these made the place all over glorious. And as we were about to enter the temple, Jesus raised His lovely voice and said, “Only the 144,000 enter this place,” and we shouted, “Alleluia!” 1T 68.2"
"After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;"
Both passages describe a vision of heaven with a multitude clothed in white robes. While EGW's vision is more detailed and specific, the core imagery aligns with Revelation 7:9.
