Romans 11
17 Ref But if some of the branches were broken off, and you, an olive-tree of the fields, were put in among them, and were given a part with them in the root by which the olive-tree is made fertile,
18 Ref Do not be uplifted in pride over the branches: because it is not you who are the support of the root, but it is by the root that you are supported.
19 Ref You will say, Branches were broken off so that I might be put in.
20 Ref Truly, because they had no faith they were broken off, and you have your place by reason of your faith. Do not be lifted up in pride, but have fear;
21 Ref For, if God did not have mercy on the natural branches, he will not have mercy on you.
22 Ref See then that God is good but his rules are fixed: to those who were put away he was hard, but to you he has been good, on the condition that you keep in his mercy; if not, you will be cut off as they were.
23 Ref And they, if they do not go on without faith, will be united to the tree again, because God is able to put them in again.
24 Ref For if you were cut out of a field olive-tree, and against the natural use were united to a good olive-tree, how much more will these, the natural branches, be united again with the olive-tree which was theirs?
