In the book Isaiah we find the Hebrew name Sinim.
Sin is Hebrew name for China.
These from the north and the west and these from the land of Sinim. Shout O Heavens and rejoice O earth, for Adonai has comforted his people. And has taken back His afflicted ones in love. According to the Scottish missionary, Reverend Thomas Torrance, who visited Chengdu in 1918, the Chiang-Min are descendants of the ancient Israelites who arrived in China several hundred years before the common era. He finds many customs common to ancient Israelite religion.
