Adam Clarke Bible Commentary

Behold, these shall come from far - "Babylon was far and east, ממזרח mimmizrach, (non sic Vett.), Sinim, Pelusians, to the south." - Secker. The land of Sinim - Prof. Doederlein thought of Syene, the southern limit of Egypt, but does not abide by it. Michaelis thinks it is right, and promises to give his reasons for so thinking in the second part of his Spicilegium Geographiae Hebraeorum Exterae. See Biblioth. Oriental. Part 11 p. 176. סין sin signifies a bush, and סינים sinim, bushes, woods, etc. Probably this means that the land where several of the lost Jews dwell is a woodland. The ten tribes are gone, no one knows whither. On the slave coast in Africa, some Jewish rites appear among the people, and all the males are circumcised. The whole of this land, as it appears from the coast, may be emphatically called ארץ שינים erets sinim, the land of bushes, as it is all covered with woods as far as the eye can reach. Many of the Indians in North America, which is also a woodland, have a great profusion of rites, apparently in their basis Jewish. Is it not possible that the descendants of the ten lost tribes are among those in America, or among those in Africa, whom European nations think they have a right to enslave?
