Romans 2:25; Romans 9:27; Romans 11:25

25 For circumcision verily profiteth , if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
27 Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved :
25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in .
