Revelation 11:5-7

Amplified Bible

⁵ And if anyone wants to harm them, fire comes out of their mouth and devours their enemies; so if anyone wants to harm them, he must be killed in this way.^{(A) 6} These [two witnesses] have the power [from God] to shut up the sky, so that no rain will fall during the days of their prophesying [regarding judgment and salvation]; and they have power over the waters (seas, rivers) to turn them into blood, and to strike the earth with every [kind of] plague, as often as they wish.^(B)

⁷ When they have finished their testimony and given their evidence, the beast that comes up out of the abyss (bottomless pit) will wage war with them, and overcome them and kill them.^(C)
