In my last post, we examined Isra’el Freed in Yesha’yahu 48:12-22. In this post, we learn about The Servant of the Lord in Yesha’yahu 49:1-7.
Chapter 49 is a Messianic prophecy. It portrays the Prince of Peace, Yeshua HaMashiach.
1Coastlands, listen to Me; listen, you peoples far away: Adonai called Me from the womb; before I was born, He had spoken My name.
Coastlands is the same word translated islands in Yesha’yahu 41:1. It refers to the distant places of the earth. The Servant (see 49:3 below) spoke here and addressed all the peoples of the earth. He began by recounting His calling that started even before He was born.
In Psalm 22:9, another Messianic prophecy, we read that Yeshua had confidence in the Father even as an infant. Here, Yesha’yahu reiterates that, even as an infant, Yeshua knew the Father called him.
2 He has made My mouth like a sharp sword while hiding Me in the shadow of His hand; He has made Me like a sharpened arrow while concealing Me in His quiver.
The sword imagery is also used for the prophet’s word and Adonai’s Word in the Brit Hadashah. Since the sword was an offensive weapon, the implication is that the word is in some sense aggressive. One of the Hebrew words for the mouth (peh) also signified the term edge, as in “edge of the sword.” Thus, there may be a play on words in this verse.
The Servant was made to be a weapon in the arsenal of Adonai; the warrior to wage war against the chaos of the world. Indeed, His spoken Word was, like His written Word. See, the Word of Adonai is alive! It is at work and is sharper than any double-edged sword – it cuts right through to where soul meets spirit and joints meet marrow, and it is quick to judge the inner reflections and attitudes of the heart.” ~ Hebrews 4:12 (CJB)
3 He said to Me, “You are My servant, Isra’el, through whom I will show my glory.”
The Servant is identified as Isra’el. However, the Brit Hadasah authors recognized a second and more profound identification of the Servant as they associated these texts with Yeshua (see Matthew 8:17; 12:17-21; John 12:38; Acts 8:30-35).
4 But I said, “I have toiled in vain, spent My strength for nothing, futility.” Yet My cause is with Adonai; My reward is with My God.
Did Yeshua think He labored in vain? Humanly, He would have had a reason. He was betrayed by one of His disciples. And there was only one at the Cross. Indeed, our Lord must have struggled with the whispers of HaSatan, saying, “You failed. The masses have rejected You and even Your disciples have forsaken You.” 
5 So now Adonai says – I formed You in the womb to be His servant, to bring Ya‘akov back to Him, to have Isra’el gathered to Him so that I will be honored in the sight of Adonai, My God having become My strength –
In verse 3, the Servant identified himself as Isra’el; here, the Servant speaks as if He is the agent of Isra’el’s restoration. This seeming inconsistency is resolved once it is realized that it is the remnant, and ultimately the remnant of one – Yeshua – who functions in this way.
6 He has said, “It is not enough that you are merely My servant to raise up the tribes of Ya‘akov and restore the offspring of Isra’el. I will also make You a light to the nations, so My salvation can spread to the ends of the earth.”
As a nation, Isra’el’s original mission was to be a light to the rest of the world. But she turned inward. Not wanting to be polluted by the heathen, she lost compassion and vision for them. The nation of Isra’el failed. But the true Isra’el -Yeshua HaMashiach – never lost sight of His calling. He lived His life as the Light of the entire world and died to save all humanity.
7 Here is what Adonai, the Redeemer of Isra’el, His Holy One, says to the One despised, whom the nations detest, to the servant of tyrants: “When kings see You, they will stand up; princes too will prostrate themselves, because of Adonai, who is faithful, the Holy One of Isra’el, who has chosen You.” ~ Isaiah 49:1-7 (CJB)
Although Yeshua was despised and rejected in His First Coming, when He comes again, every knee will bow – in heaven, on earth, and under the earth – and every tongue will acknowledge that Yeshua the Messiah is Adonai – to the glory of God the Father. ~ Philippians 2:10-11 (CJB)
In my next post, we learn about The Restoration of Isra’el in Yesha’yahu 49:8-26.
