And their slain ones will be thrown out; and as for their carcasses, their stink will ascend; and the mountains must melt because of their blood.”​—Isaiah 34:2, 3.

Jehovah’s law has set the standard: “You must give soul for soul.” (Exodus 21:23-25; Genesis 9:4-6) True to this law, he will cause the blood of the nations to flow​—to their death. The stench of their unburied, dead bodies will fill the air​—a truly shameful death! (Jeremiah 25:33) The blood asked back in repayment will be enough to melt, or dissolve, as it were, the mountains. (Zephaniah 1:17) With the complete destruction of their military forces, the worldly nations will see the fall of their governments, which in Bible prophecy are sometimes pictured as mountains.​—Daniel 2:35, 44, 45; Revelation 17:9.
