"God's law. For a thousand years he can enjoy the fruit of the curse which he has caused. Limited alone to the earth, he will not have the privilege of ranging to other planets, to tempt and annoy those who have not fallen. During this time, Satan suffers extremely. Since his fall his evil traits have been in constant exercise. But he is then to be deprived of his power, and left to reflect upon the part which he has acted since his fall, and to look forward with trembling and terror to the dreadful future, when he must suffer for all the evil that he has done and be punished for all the sins that he has caused to be committed. EW 290.1"
"And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,"
Both passages refer to the binding of Satan for a thousand years. EGW expands on the suffering and limitations Satan will experience during this period, which is a reasonable interpretation of the symbolic binding described in Revelation 20:2.
"I heard shouts of triumph from the angels and from the redeemed saints, which sounded like ten thousand musical instruments, because they were to be no more annoyed and tempted by Satan and because the inhabitants of other worlds were delivered from his presence and his temptations. EW 290.2"
"And I heard as it were the voice of a great multitude, and as the voice of many waters, and as the voice of mighty thunderings, saying, Alleluia: for the Lord God omnipotent reigneth."
Both passages describe joyous sounds and celebrations. Revelation 19:6 speaks of a great multitude praising God, while EGW describes shouts of triumph from angels and redeemed saints. The common theme is celebration and victory.
"Then I saw thrones, and Jesus and the redeemed saints sat upon them; and the saints reigned as kings and priests unto God. Christ, in union with His people, judged the wicked dead, comparing their acts with the statute book, the Word of God, and deciding every case according to the deeds done in the body. Then they meted out to the wicked the portion which they must suffer, according to their works; and it was written against their names in the book of death. Satan also and his angels were judged by Jesus and the saints. Satan's punishment was to be far greater than that of those whom he had deceived. His suffering would so far exceed theirs as to bear no comparison with it. After all those whom he had deceived had perished, Satan was still to live and suffer on much longer. EW 290.3"
"And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years."
This is a clear and direct allusion. Both passages describe thrones, the saints reigning with Christ, and judgment being given. EGW elaborates on the judgment process, but the core elements are directly derived from Revelation 20:4.
