Hebrews 4:12

4:12 For the word of God is living and active and sharper than any double-edged sword, piercing even to the point of dividing soul from spirit, and joints from marrow; it is able to judge the desires and thoughts of the heart.

Revelation 1:16

1:16 He held seven stars in his right hand, and a sharp double-edged sword extended out of his mouth. His face shone like the sun shining at full strength.
