Here is a Messianic prophecy with my addition of who is speaking and some commentary.
Isa 49:1 Listen, O isles, unto me [Yeshua]; and hearken, ye people, from far; YHWH [Yeshua's Father] hath called me from the womb; from the bowels of my mother hath he made mention of my name.
Isa 49:2 And he [Father YHWH] hath made my mouth like a sharp sword; in the shadow of his hand hath he hid me, and made me a polished shaft; in his quiver hath he hid me;
Isa 49:3 And said unto me [Yeshua], Thou art my servant, O Israel [put for Messiah who s the King and primary representative of the whole Israel of God], in whom I will be glorified.
Isa 49:4 Then I said, I have laboured in vain, I have spent my strength for nought, and in vain: yet surely my judgment is with YHWH [the Father], and my work with my God [YHWH is Yeshua's God].
Isa 49:5 And now, saith YHWH [the Father] that formed me [Yeshua] from the womb to be his servant, to bring Jacob [Israel] again to him [to the Father], Though Israel be not gathered, yet shall I [Yeshua] be glorious in the eyes of YHWH [the Father], and my God [Yeshua's God, YHWH] shall be my strength.
Isa 49:6 And he [Father YHWH] said, It is a light thing that thou [Yeshua] shouldest be my servant to raise up the tribes of Jacob [Israel], and to restore the preserved of Israel: I [Father YHWH] will also give thee [Yeshua] for a light to the Gentiles, that thou [Yeshua] mayest be my salvation [the Father's instrument to save the world] unto the end of the earth.
Isa 49:7 Thus saith YHWH [the Father], the Redeemer of Israel [Father YHWH is Israel's Redeemer. He accomplishes the redemption through His servant Yeshua. That makes Yeshua our redeemer as well. Similarly, Father YHWH sent men to save Israel at various times in their history and He called them "saviors" even though it was Father YHWH that initiated the saving making Him the Ultimate Savior. See 2 Kings 13:5; Nehemiah 9:27; Isaiah 19:20], and his [Israel's] Holy One, to him whom man despiseth [Yeshua], to him whom the nation abhorreth [Yeshua], to a servant of rulers [Yeshua], Kings shall see and arise, princes also shall worship, because of YHWH that is faithful, and the Holy One of Israel, and he [Father YHWH] shall choose thee [Yeshua].
