I am doing a study on Isaiah 52 in the upcoming week and am looking through the commentaries on it. Here are the ones I have found helpful (Or not helpful).
Word Biblical Commentary, by J. Watts. Good discussion of the Hebrew text. Explores possible divisions in the text. Some references to NT echoes.
New Interpreter’s Bible: Isaiah 40-66, by Christopher Seitz. Decent discussion
Isaiah 40:66, by Walter Brueggemann. Surprisingly decent application. Not sure of all the later Markan echoes.
Deutero-Isaiah Anchor Bible. Meh. Decent section on 52:7.
