Shevuoth, fol. 39, col. 1.
If one find a foundling in a locality where the majority are Gentiles, then the child is (to be reckoned) a Gentile; if the majority be Israelites, it is to be considered as an Israelite; and so also it is to be, providing the numbers are equal.
Machsheerin, chap. 2, Mish. 7.
"One generation passeth away, and another generation cometh, but the earth abideth forever" (Eccl. i. 4). One empire cometh and another passeth away, but Israel abideth forever.
Perek Hashalom.
The world was created only for Israel: none are called the children of God but Israel; none are beloved before God but Israel.
Gerim, chap. 1.
The Jew that has no wife abideth without joy, without a blessing, and without any good. Without joy, as it is written (Deut. xiv. 26), "And thou shalt reject, thou and thy household;" without blessing, as it is written (Ezek. xliv. 30), "That He may cause a blessing to rest on thy household;" without any good, for it is written (Gen. ii. 8), "It is not good that man should be alone."
