Iftah Ya Simsim
The show focused on Arab heritage, like the wedding rituals of countries in the region, and included Arab poems and songs. "Iftah Ya Simsim" premiered in Kuwait in September 1979, and was broadcast in all Arabic-speaking countries excluding Egypt. The show's opening consisted of a catchy tune that became beloved of its young viewers. As the song played, the opening footage showed children across the Arab world running past familiar landmarks like the Pyramids and playing in playgrounds and ancient alleyways before running into a white fort that had its gates open wide. The show's set consisted of an intricately traditional Arabian neighborhood called "Sharee Eshreen" (20th Street).
Sinim
Some scholars have claimed that Sinim is a variant name for not-so-distant Phoenicia. However, it is notable that Isaiah writes "[T]hese shall come from far; and lo, these from the north and the west; and these from the land of Sinim". This seems to indicate that these people did not live in the north or the west. Isaiah lived in the 8th-7th century B.C. and Phoenicia existed during this period, lying directly west of Judah and Israel. Isaiah would have been familiar with this region, its name and location, so unless he is using some euphemism, it would seem Phoenicia is not a good candidate.
