'Two Edged Sword' in the Bible

So Ehud made himself a two-edged sword, a cubit long, which he put on at his right side under his robe.

Let the high praises of God be in their mouth, And a two-edged sword in their hand;

But in the end she is bitter as wormwood, Sharp as a two-edged sword.

For the word of God is living, and active, and sharper than any two-edged sword, and piercing even to the dividing of soul and spirit, of both joints and marrow, and quick to discern the thoughts and intents of the heart.

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.
