Romans 11:16-17

11:16 If the first portion of the dough offered is holy, then the whole batch is holy, and if the root is holy, so too are the branches.

11:17 Now if some of the branches were broken off, and you, a wild olive shoot, were grafted in among them and participated in the richness of the olive root,

Romans 11:24
