Ephesians 6:17-18

17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God;  18 with all prayer and requests, praying at all times in the Spirit, and being watchful to this end in all perseverance and requests for all the saints: 

2 Thessalonians 2:8

8 Then the lawless one will be revealed, whom the Lord will kill with the breath of his mouth, and bring to nothing by the brightness of his coming; 

Isaiah 11:4

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

Isaiah 59:16-21

16 He saw that there was no man, and wondered that there was no intercessor: therefore his own arm brought salvation to him; and his righteousness, it upheld him.  17 He put on righteousness as a breastplate, and a helmet of salvation on his head; and he put on garments of vengeance for clothing, and was clad with zeal as a mantle.  18 According to their deeds, accordingly he will repay, wrath to his adversaries, recompense to his enemies; to the islands he will repay recompense.  19 So shall they fear the name of Yahweh from the west, and his glory from the rising of the sun; for he will come as a rushing stream, which the breath of Yahweh drives.  20 A Redeemer will come to Zion, and to those who turn from disobedience in Jacob, says Yahweh.  21 As for me, this is my covenant with them, says Yahweh: my Spirit who is on you, and my words which I have put in your mouth, shall not depart out of your mouth, nor out of the mouth of your seed, nor out of the mouth of your seed's seed, says Yahweh, from henceforth and forever.
