Isaiah 26:14

“[They are] dead, they shall not live; [they are] deceased, they shall not rise, &c.] The above tyrannical lords, the kings of the earth and their mighty men, associates of the Romish antichrist, who shall be gathered together, and slain at the battle at Armageddon; these shall not live again in this world, nor rise from their graves, and return to their former state, power, and authority; or tyrannise over, molest, disturb, oppress, and persecute the people of God any more; though they shall live again at the end of the thousand years, and shall awake to everlasting shame and contempt, and come forth to the resurrection of damnation.

“The tyrants who usurped the rule over Israel have now utterly disappeared. "Dead men live not again, shades do not rise again: so hast Thou visited and destroyed them, and caused all their memory to perish." The meaning is not that Jehovah had put them to death because there was no resurrection at all after death; for, as we shall see further on, the prophet was acquainted with such a resurrection. In mēthim (dead men) and rephâ'im (shades) he had directly in mind the oppressors of Israel, who had been thrust down into the region of the shades (like the king of Babylon in chapter 14), so that there was no possibility of their being raised up or setting themselves up again.
