Romans 11:
15 For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead? 16 For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:
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.
26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 27 For this is my covenant unto them, when I shall take away their sins.
28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes. 29 For the gifts and calling of God are without repentance.
