'Two edged' in the Bible

For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and 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 twoedged sword: and his countenance was as the sun shineth in his strength.

“Write to the angel of the church in Pergamum:“The One who has the sharp, double-edged sword says:

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.
