'Assemble' in the Bible

{And then} on that day I will make Jerusalem a stone weight for all the peoples. All those lifting it up will grievously hurt themselves, and all the nations of the earth will assemble against it.

And I will assemble all the nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity; and the rest of the people shall not be cut off from the city.
