6Let athe high praises of God be in their throats
and btwo-edged swords in their hands,

Hebrews 4:12

12For cthe word of God is living and dactive, esharper than any ftwo-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and gdiscerning the thoughts and intentions of the heart.
