Another answer:

The question appears to be combining two different sets of New Testament imagery. It's God's word that is said to be sharper than a two-edged sword...

Hebrews 4:12 - For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.

...which gives rise to the later use of the imagery of a sword proceeding from the mouth as a tongue:

Revelation 1:16 - He had in His right hand seven stars, out of His mouth went a sharp two-edged sword, and His countenance was like the sun shining in its strength.

Revelation 2:16 - Repent, or else I will come to you quickly and will fight against them with the sword of My mouth.

Revelation 19:15 - Now out of His mouth goes a sharp sword, that with it He should strike the nations. And He Himself will rule them with a rod of iron. He Himself treads the winepress of the fierceness and wrath of Almighty God.

Revelation 19:21 - And the rest were killed with the sword which proceeded from the mouth of Him who sat on the horse. And all the birds were filled with their flesh.

On the other hand, here is some of what is said about the literal tongue:

James 1:26 - If anyone among you thinks he is religious, and does not bridle his tongue but deceives his own heart, this one's religion is useless.

James 3:5-8 - Even so the tongue is a little member and boasts great things. See how great a forest a little fire kindles! And the tongue is a fire, a world of iniquity. The tongue is so set among our members that it defiles the whole body, and sets on fire the course of nature; and it is set on fire by hell. For every kind of beast and bird, of reptile and creature of the sea, is tamed and has been tamed by mankind. But no man can tame the tongue. It is an unruly evil, full of deadly poison.
