Psalms II, 51-100 (Anchor Bible, Vol 17)

Dahood does work deeply into Semetic philology, and while this may bog down the non-academics, he offers an incredible wealth of poetic wisdom from this perspective. Often I was simply struck by the depth of his variant translations and readings of individual Psalms. For me, this is a strong resource to use along side of many other quality texts as mentioned by Olaf01. Dahood's takes some great risks opening himself up for brilliance or criticism. Either way, it makes for exciting and insightful comparisons among the other seminal texts.
