Sinai inscription 347 (S. 347)
However, this inscription is accompanied by a drawing (on the left of H), which must be included in the discussion. I have already ruminated over this image elsewhere on the web, but it comes down to this: while this figure certainly resembles the Egyptian sign for 'life' (`ankh), it is better to see it as a goddess; the deity TNT (Tannit) is represented by a similar symbol in later West Semitic iconography (with forearms raised), and the name TNT is already found on a Bronze Age statuette from Sinai (347, in the temple of the turquoise miners at Sarabit al-Khadim).
