This is the third Servant Song (cf. Isaiah 42:1-4; Isaiah 49:1-6; Isaiah 52:13 to Isaiah 53:12). Like the second Song of Solomon , this one is autobiographical, but unlike the first and second songs it contains no reference to the Servant. That it is the Servant who is speaking becomes unmistakable in Isaiah 50:10-11, the "tailpiece" of this song. But what the Servant says, even without that specific identification, leaves little doubt that it is He who is speaking. The obedient and faithful Servant, though deeply troubled, expresses confidence in His calling to proclaim the Lord"s Word and in His ultimate vindication. The reason for the Servant"s uneasiness becomes clearer in this passage. It is because obedience to God would lead to physical and emotional suffering ( Isaiah 50:5-6). The extent of this suffering comes out most clearly in the fourth song. [1][source]
