5 And now, saith the Lord that formed Me from the womb to be His servant, to bring Jacob again to Him, Though Israel be not gathered, yet shall I be glorious in the eyes of the Lord, and my God shall be My strength.
6 And He said, It is a light thing that Thou shouldest be My servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give Thee for a light to the Gentiles, that Thou mayest be My salvation unto the end of the earth.
Jesus, Messiah, was called from the womb, named from birth, and formed in the womb. His purpose was to glorify God, to bring salvation not just to the Jews, but also to the Gentiles.
In verse 5, Israel was to be brought back to God finally and forever as a result of Messiah’s coming. It was a far future prophecy here, indicated by the Hebrew verb tense for which English has no specific translation.
Even though that regathering would not be complete during Jesus’ walk on earth, still the Father would be glorified by His life, death, and resurrection. It is Jesus, Messiah, Who speaks here claiming God as His strength.
Verse 6 gives us the glorious promise that Jesus would be the Light, the way of salvation, not only for the Jews, but also for the Gentiles. This statement is quoted in Luke 2:32 and Acts 13:47.
