Isaiah 49:2

¹²For the word of God is living and active, and sharper than any two-edged sword, piercing even to the dividing of soul and spirit, of both joints and marrow, and is able to discern the thoughts and intentions of the heart.

¹⁶He had seven stars in his right hand. Out of his mouth proceeded a sharp two-edged sword. His face was like the sun shining at its brightest.

⁴The Lord GOD has given me the tongue of those who are taught, that I may know how to sustain with words him who is weary. He awakens morning by morning, he awakens my ear to hear as those who are taught.

¹²“To the angel of the assembly in Pergamum write: “He who has the sharp two-edged sword says these things:

¹⁶I have put my words in your mouth and have covered you in the shadow of my hand, that I may plant the heavens, and lay the foundations of the earth, and tell Zion, ‘You are my people.’”

⁴but he will judge the poor with righteousness, and decide with equity for the humble of the earth. He will strike the earth with the rod of his mouth; and with the breath of his lips he will kill the wicked.

¹⁸For behold, I have made you today a fortified city, an iron pillar, and bronze walls against the whole land—against the kings of Judah, against its princes, against its priests, and against the people of the land.

¹He who dwells in the secret place of the Most High will rest in the shadow of the Almighty.

⁵Therefore I have cut them to pieces with the prophets; I killed them with the words of my mouth. Your judgments are like a flash of lightning.

¹⁹Therefore the LORD says, “If you return, then I will bring you again, that you may stand before me; and if you take out the precious from the vile, you will be as my mouth. They will return to you, but you will not return to them. ²⁰I will make you to this people a fortified bronze wall. They will fight against you, but they will not prevail against you; for I am with you to save you and to deliver you,” says the LORD.
