I checked out the Alan Cooper article that I discuss in my last post, Avoiding a Suffering God; YHWH in the Underworld. Basically, Cooper's argument is that Psalm 24:7-10 is about YHWH entering the Underworld to defeat death. Psalm 24:7-10 is well-known to people who listen to Handel's Messiah over and over (as I used to do). It says (according to my memory):
"Lift up your heads, O ye gates, that the King of Glory may come in."
"Who is this King of Glory?"
"The LORD of hosts, mighty in battle, he is this King of Glory."
Interpreters have applied this Psalm to cultic festivals or God entering Jerusalem after returning from battle. But, as Cooper points out, ancient Near Eastern gates did open by means of lifting. Therefore, Cooper looks for another option. Based on ancient Near Eastern parallels (e.g., Egyptian and Ugaritic literature), Cooper concludes that the Psalm presents YHWH going to the Underworld to defeat death. A herald exhorts the gatekeepers to lift up their heads (stand proud) and let YHWH, the King of Glory, enter. They scornfully respond, "Who is this King of Glory," and are told "The LORD of hosts, mighty in battle." YHWH then does his business and returns to his sanctuary, which is connected to the Underworld.
Cooper sees a continuation of this myth in ancient Christian stories about Jesus going to hell to set free the righteous, thereby defeating death. And, although many scholars would argue that the Hebrew Bible lacks a clear notion of the afterlife, Cooper seems to suggest that we shouldn't regard this scholarly presupposition as iron-clad.
I didn't do a full research project on the descent of gods to the Underworld, but I glanced at wikipedia's article, Descent to the underworld. It is a common theme in the ancient Near East, Greek and Roman mythology, and Asia. Sometimes, a goddess would descend into the Underworld to perform funeral rites (as did the Canaanite goddess Ishtar). Sometimes, a god or goddess would attempt to rescue someone from the Underworld. From my elementary school days, I learned that these kinds of myths were often symbols for the seasonal cycle: winter was death, but spring was life. Maybe YHWH descended into the Underworld to bring life to nature, also known as the spring season, a time of crops and food and celebration.
Some have tried to contrast YHWH with ancient Near Eastern gods by saying that the latter were more concerned about the cycles of nature, whereas YHWH's realm was history. This is true in a sense, but YHWH was also concerned about nature, just like other ancient Near Eastern gods. The Torah has a lot about Israel receiving agricultural blessings: rain in due season, crops, etc. And YHWH in the Hebrew Bible keeps the waters at bay so that life and order are preserved. Granted, the Hebrew Bible applies the "chaotic waters" myth to historical events, such as the threat of Israel's enemies. But one cannot exclude the natural element.
Whatever the Psalm meant in its original context, I like the concept of God being above death. In many of the myths about the Underworld, it's a pretty scary and intimidating place! At Jewish Theological Seminary (where Dr. Cooper currently teaches), I watched an animated depiction of Ishtar's descent to the Underworld for my Akkadian class, and, although it was rather cheesy, the Underworld still didn't strike me as a place I'd want to go! The same went with the cartoon Thundercats, which on one episode depicted an ancient Egyptian view of the Underworld. But YHWH and later Jesus Christ could go there boldly and without fear, with an authority that commanded respect from the gatekeepers of death.
