Isaiah 21:17

(17) And the residue . . .—The Hebrew word is the same as the characteristic “remnant” of Isaiah’s earlier prophecies. The words point primarily to the subjugation of Arabia by Sargon and Sennacherib, who narrate their victories over the Arabian tribes (Records of the Past, vii. 34). In Jeremiah 49:28-29 we have an echo of the prediction, which, in that case, pointed to their conquest by Nebuchadnezzar.
