Revelation 11:5

11:5 If anyone wants to harm them, fire comes out of their mouths and completely consumes their enemies. If anyone wants to harm them, they must be killed this way.

Revelation 13:10

13:10 If anyone is meant for captivity,

into captivity he will go.

If anyone is to be killed by the sword,

then by the sword he must be killed.

This requires steadfast endurance and faith from the saints.
