3, 4. Some 2,700 years before 1914, what did Jehovah inspire Isaiah to write about “all the nations”?

³ Over 2,700 years ago, Jehovah God pointed forward to the era when steel war tanks and airplanes would be used for the first time in martial combat, and when trench warfare would become specialized, soldiers would have to use gas masks, and long-range cannons such as the “Big Bertha” would be employed in total conflict. Yes, some 27 centuries before World War I, Jehovah God inspired the prophet Isaiah to describe something else that would be happening at that time, saying:

And he will certainly render judgment among the nations and set matters straight respecting many peoples. And they will have to beat their swords into plowshares and their spears into pruning shears. Nation will not lift up sword against nation, neither will they learn war anymore.

Isaiah 2:1-5.
