Excerpt - Apocalyptic Commentary of the Book of Isaiah by Avraham Gileadi, Ph.D.

49:22–23 Thus says my Lord Jehovah: I will lift up my hand to the nations, raise my ensign to the peoples; and they will bring your sons in their bosoms and carry your daughters on their shoulders. Kings shall be your foster fathers, queens your nursing mothers. They will bow down before you, their faces to the ground; they will lick the dust of your feet. Then shall you know that I am Jehovah, and that they who hope in me are not disappointed.

Jehovah’s raising his hand and ensign—his end-time servant—brings about his people’s return from exile: “In that day the sprig of Jesse, who stands for an ensign to the peoples, shall be sought by the nations, and his rest shall be glorious. In that day my Lord will again raise his hand to reclaim the remnant of his people—those who shall be left out of Assyria, Egypt, Pathros, Cush, Elam, Shinar, Hamath, and the islands of the sea. He will raise the ensign to the nations and assemble the exiled of Israel; he will gather the scattered of Judah from the four directions of the earth” (Isaiah 11:10–12; emphasis added).
The kings and queens of the “nations” or “Gentiles” (goyim) escort Jehovah’s “sons” and “daughters”—his elect who ascend to the son/servant category—in a new exodus out of all nations when Jehovah empowers his servant (Isaiah 11:15–16; 48:20–21; 51:9–11; 52:11–15; 55:3–5, 12). Having attained the seraph category, these spiritual kings and queens exercise power over enemies and obstacles in the pattern of Moses and Elijah, enabling Jehovah’s people to walk through deserts, mountains, seas, rivers, and fire in the new exodus to Zion (v 11; Isaiah 11:15; 35:6–10; 41:10–13, 17–18; 43:2; 51:10).
A disparity exists between these same spiritual kings and queens of the Gentiles and other Gentiles who, instead of repenting, oppose Jehovah’s people (Isaiah 29:7–8; 54:15–17; 66:5). While the Gentiles’ kings and queens fulfill their roles of proxy saviors under the terms of the Davidic Covenant on the seraph level, those Gentiles who turn into Jehovah’s enemies end up bowing down before his people and licking the dust of their feet (Isaiah 45:14; 60:14; 66:5). Those who “know” Jehovah in the end are those who “hope in” or “wait for” (qiwweh) him through a time of adversity (Isaiah 19:21; 25:9; 52:6).
