The Psalm is one that appears in the Dead Sea Scrolls, suggesting that from earliest times it has captured the imagination of the religiously minded. I need to investigate further the numbering of the psalms, to find out if there is any significance in this fine piece being early in the sequence.
At many points the traditional Hebrew, Masoretic text is corrupt, and emendation has led to differences between Christian and Jewish interpretations, particularly around Ps 2:7 and the references to the Son. Christian translations link the reference not just to David but to Jesus. It would be interesting to find out more about the scope for various interpretations of the Hebrew. Readings of a couple of words of the Psalm are also affected by revocalisation, the re-interpretation of vowel signs added to the original Hebrew.
