This is somewhat off-topic so I'd appreciate off-list replies.
The Septuagint, Peshitta, and Vulgate agree in translating Psalms 97:11 as if it read )WR ZRX ['or zarah] instead of _WR ZR( ['or zarua`]. But the Targum has an addition: NHWR DNX WM+MR LCDYQY).
Can someone suggest where I can get an elaboration about that WM+MR? Does it in fact mean "hidden away" as I have guessed? Is the Targum referring to a midrash about the light of creation before the sun was created being put away until the end of days? Do any other translations have a similar addition?
