Sinim appears in Isaiah's prophecy of Israel's restoration, when exiles will return 'from the north and from the west, and these from the land of Sinim.' The identification has puzzled interpreters for centuries. Early proposals included China (based on phonetic similarity), but this seems unlikely given historical context. More probable is an emendation to 'Syenites' (people of Syene/Aswan in southern Egypt), which would provide a neat geographical balance—north, west, and south. The text as it stands reaches toward the known ends of the earth, emphasizing the comprehensiveness of the return.
