Jesus and Israel

You recently had a family devotion about God's plan under daily devotions on Isaiah 49:5-6. It said this was a conversation between God the Father and Jesus the Son. How do we come to this conclusion when verse 3 says the servant is Israel?

As the promised Messiah, Jesus went by many different names and titles in the Old Testament. “Israel” in Isaiah 49:3 is one of those names. Calling the Messiah by that name underscores the means by which God sent the promised Savior into the world: Jesus, the eternal Son of God, came into the world and took on human flesh as a descendant of Jacob (Matthew 1:1-2; Luke 3:34).
