'Gather' in the Bible

It will come about at that time that I will make Jerusalem a heavy weight; so everyone who burdens themselves with it will be crushed, even though all of the nations of the earth gather themselves against it.

I will gather all the nations against Jerusalem, to lay siege against it. The city will be captured, the houses will be ransacked, the women raped, and half of the city will go into exile, but the remaining people will not be cut off from the city.
