52:13 Behold, my servant. The last three verses of Isaiah 52 should really be the introduction to Isaiah 53, the whole constituting not only an amazing prophecy but also the fullest and clearest exposition of the substitutionary death of Christ in all the Bible.
52:13 be very high. The introduction to Messiah’s sufferings first foretells the final triumph. His “prudent” dealings will ultimately result in His being given the name above every name (see Philippians 2:5-9). “Exalted,” then “extolled,” then “be very high” seem to refer, respectively, to Christ’s resurrection, ascension, and session at the right hand of the Father.
