Discovery BoxRevelation 9:18-19 
Context9:18 A third of humanity was killed by these three plagues, that is, 1 by the fire, the smoke, and the sulfur that came out of their mouths. 9:19 For the power 2 of the horses resides 3 in their mouths and in their tails, because their tails are like snakes, having heads that inflict injuries.
1 tn The phrase ἐκ τοῦ πυρὸς καὶ τοῦ καπνοῦ καὶ τοῦ θείου τοῦ ἐκπορευομένου ἐκ τῶν στομάτων αὐτῶν (“by the fire, the smoke, and the sulfur that came out of their mouths”) is taken as epexegetical (explanatory) to the phrase τῶν τριῶν πληγῶν τούτων (“these three plagues”).
2 tn See BDAG 352 s.v. ἐξουσία 2, “potential or resource to command, control, or govern, capability, might, power.”
3 tn Grk “is.”
