Prophet Ezekiel foretold World Wars I - III in chapter 21, verse 14 :
"14 Therefore, son of man, prophesy thou, and smite thou hand to hand (and strike thou one hand to the other, that is, clap thy hands), and the sword be doubled, and the sword of the slayers be trebled; this is the sword of great slaying, that shall make them astonied, and to fail in heart, and multiplieth fallings." (Wycliffe Bible 1378 A.D.)
"14 Thou therefore, O son of man, prophesy, and strike thy hands together, and let the sword be doubled, and let the sword of the slain be tripled: this is the sword of a great slaughter, that maketh them stand amazed,
15 And languish in heart, and that multiplieth ruins. In all their gates I have set the dread of the sharp sword, the sword that is furbished to glitter, that is made ready for slaughter.
16 Be thou sharpened, go to the right hand, or to the left, which way soever thou hast a mind to set thy face.
17 And I will clap my hands together, and will satisfy my indignation: I the Lord have spoken." (Douay-Rheims 1899 A.D.)
