'Two edged' in the Bible

For the word of God is living and powerful, and sharper than any two edged sword, piercing even to the dividing asunder both of the soul and spirit, both of the joints and marrow, and is a discerner of the thoughts and intents of the heart.

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

And to the angel of the church at Pergamos write, These things saith he who hath the sharp two-edged sword.

And out of his mouth goeth forth a sharp two-edged sword, that with it he may smite the nations. And he shall rule them with a rod of iron: and he treadeth the wine-press of the fierceness of the wrath of God, the Almighty.
