Isaiah 49:2
1 Listen to me, you coastlands! Pay attention, you people who live far away! The Lord summoned me from birth; he commissioned me when my mother brought me into the world. 2 He made my mouth like a sharp sword, he hid me in the hollow of his hand; he made me like a sharpened arrow, he hid me in his quiver. 3 He said to me, “You are my servant, Israel, through whom I will reveal my splendor.” 4 But I thought, “I have worked in vain; I have expended my energy for absolutely nothing.” But the Lord will vindicate me; my God will reward me. 5 So now the Lord says, the one who formed me from birth to be his servant— he did this to restore Jacob to himself, so that Israel might be gathered to him; and I will be honored in the Lord’s sight, for my God is my source of strength—

I am the first and the last,
Notes and References
"... Two details in the description of Christ in Revelation 1 allude to the text of Isaiah. In describing the apparel of the “likeness of a son of man” as “being clothed in a long flowing robe” in Revelation 1:13b, the author links his vision of Christ with the theophany of Isaiah where YHWH’s “skirt” fills the temple (Isaiah 6:1). The description “and a sharp two-edged sword was coming out of his mouth” in Revelation 1:16b alludes primarily to Isaiah 49:2 where the Suffering Servant states that YHWH made his mouth like a “sharp sword” ..."
