'In the Latter Days' in the Bible

And thou shalt come up against my people of Israel, as a cloud to cover the land; it shall be in the latter days, and I will bring thee against my land, that the heathen may know me, when I shall be sanctified in thee, O Gog, before their eyes.

Then they will know [without any doubt] that I am the Lord their God because I made them go into exile among the nations, and then gathered them to their own land. I will leave none of them there [among the nations] any longer.
