I will soon be starting a brief sermon series on the Psalms of the Sons of Korah. I was looking to possibly pick up another commentary on Psalms.
I already have:
Keil and Delitzsch
I also have some devotional or sermonic stuff, like Spurgeon or Wiersbe.
I was looking more for one more on the academic side but up to date, (like the first three I listed). Any recommendations?
