Isaiah 49:12

“Behold, these shall come from far, &c.] This is a prophecy of the conversion of the Jews, or of the Gentiles, or of both, in the latter day, in the several parts of the world; who shall come to Christ, and to his churches, and join in fellowship with them: the allusion is to the return of the Jews from their captivity in Babylon, and from all other parts at that time; some are said to come “from far”, from the east, as it is generally interpreted, from the several eastern nations, as Persia, Judea lying west from them, on the western or Mediterranean sea: and, lo, these from the north; from Media, as some; or rather from Babylon, which lay north of Judea: and from the west; or “from the…”

“Sinim--The Arabians and other Asiatics called China Sin, or Tchin; the Chinese had no special name for themselves, but either adopted that of the reigning dynasty or some high-sounding titles. This view of "Sinim" suits the context which requires a people to be meant "from far," and distinct from those "from the north and from the west" [GESENIUS].”

“Behold, these shall come from far - That is, one part shall come from a distant land, and another from the north and west. This is a statement of the fulfillment of the promise made to him Isaiah 49:6-7, that he should be for a light to the Gentiles, and that kings and princes should rise up and honor him. The words ‘from far,’ denote a distant land, without specifying the particular direction from which they would come. The most distant nations should embrace his religion, and submit to him. Lowth and Seeker understand it of Babylon; Grotius of the East, that is, Persia, and the other countries east of Judea. But it more properly denotes any distant country; and the sense is, that converts…”

“These - My people shall be gathered from the most remote parts of the earth. He speaks here, and in many other places, of the conversion of the Gentiles, with allusion to that work of gathering, and bringing back the Jews from all parts where they were dispersed, into their own land. Sinim - Either of the Sinites as they are called, Gen 10:17, who dwelt about the wilderness. Or of Sin, a famous city of Egypt, which may be put for all Egypt, and that for all southern parts. Isaiah 49:14”

“49:12 The remnant would come from the north (i.e., from Babylon and Persia), from the west by sea, and from as far south as Egypt.”
