"Without doubt, they [the Jews] will return to their own land; because when their unbelief ceases, their dispersion, the dreadful and signal punishment of their unbelief, will cease too. . . . And as they have hitherto continued a distinct nation that they might continue a visible monument to His displeasure, for their rejecting and crucifying their Messiah, so after their conversion will they still be a distinct nation, that they may be a visible monument of God's wonderful grace and power in their calling and conversion.

But yet, we are not to imagine that the old walls of separation will be set up again. But all nations will be as free to come to Judea, or to dwell in Jerusalem, as into any other city or country, and may have the same privilege there as they themselves. For they [the Jewish people] shall look upon all the world to be their brethren, as much as the Christians in Boston and the Christians in other parts of New England look on each other as brethren." 

"Nothing is more certainly foretold than this national conversion of the Jews is in the eleventh chapter of Romans. And there are also many passages of the Old Testament that can't be interpreted in any other sense, that I can't now stand to mention. . . . The world affords nothing else like it- a remarkable hand of providence. When they shall be called, then shall that ancient people that were alone God's people for so long a time be God's people again, never to be rejected more, one fold with the Gentiles, and then also shall the remains of the ten tribes, wherever they are, be brought in together, and shall be united as one people as they formerly were under David and Solomon (Hos. 1.11), and so in the last chapter of Hosea, and other parts of his prophecy."

"And it is the more evident, that the Jews will return to their own land again, because they never have yet possessed one quarter of that land, which was so often promised them, from the Red Sea to the river Euphrates (Ex. 23.31; Gen. 15.18; Deut. 11.24; Josh. 1.4). Indeed, it was partly fulfilled in Solomon's time, when he governed all within those bounds for a short time; but so short, that it is not to be thought that this is all the fulfillment of the promise that is to be. And besides, that was not a fulfillment of the promise, because they did not possess it."
