'Sharp Two Edged Sword' in the Bible

And he had in his right hand seven stars: and out of his mouth proceeded a sharp two-edged sword: and his countenance was as the sun shineth in his strength.

and to the angel of the church in Pergamum write: These things saith he that hath the sharp two-edged sword:

And out of his mouth goes a sharp two-edged sword, that with it he might smite the nations; and he shall shepherd them with an iron rod; and he treads the wine-press of the fury of the wrath of God the Almighty.
