Isaiah 49:3

Amplified Bible

³
And [the Lord] said to Me, “You are My ^[a]Servant, Israel,
In Whom I will show My glory.”^(A)

Isaiah 49:3 At first glance it would seem that Israel is the servant. However, many scholars maintain that the Messiah is being addressed as Israel because He represents and fulfills what Israel as a nation was meant to be: the source of salvation to the world. Note also that in v 6 the Servant is destined to restore Israel, which indicates that He is not Israel itself.
