Isaiah 11:10
8 A baby will play over the hole of a snake; over the nest of a serpent an infant will put his hand. 9 They will no longer injure or destroy on my entire royal mountain. For there will be universal submission to the Lord’s sovereignty, just as the waters completely cover the sea. 10 At that time a root from Jesse will stand like a signal flag for the nations. Nations will look to him for guidance, and his residence will be majestic. 11 At that time the Lord will again lift his hand to reclaim the remnant of his people from Assyria, Egypt, Pathros, Cush, Elam, Shinar, Hamath, and the seacoasts. 12 He will lift a signal flag for the nations; he will gather Israel’s dispersed people and assemble Judah’s scattered people from the four corners of the earth.
Revelation 5:5
3 But no one in heaven or on earth or under the earth was able to open the scroll or look into it. 4 So I began weeping bitterly because no one was found who was worthy to open the scroll or to look into it. 5 Then one of the elders said to me, “Stop weeping!

He had seven horns and seven eyes, which are the seven spirits of God sent out into all the earth. 7 Then he came and took the scroll from the right hand of the one who was seated on the throne,
Notes and References
"... The most pertinent element for our study is Romans 15:12, with the citation of Isaiah 11:10: 'Isaiah says, "The Root of Jesse will spring up, one who will rise to rule over the nations; in him the Gentiles will hope.' 'Root of Jesse' is a messianic designation for a royal eschatological deliverer, equivalent to 'Root of David' (1QSb 5:26; 4QFlorilegium 1:11; Psalms of Solomon 17:21-46; Sirach 47:22; Revelation 5:5, 22:16). Paul taps into Israel's prophetic script that Israel's kingdom will rise from its humiliating subjugation under foreign powers like Rome, which will be achieved through Mesiah Jesus ..."
