'Root' in the Bible

If the first fruit is holy, so is the lump. If the root is holy, so are the branches.

But if some of the branches were broken off, and you, being a wild olive, were grafted in among them, and became partaker with them of the root and of the richness of the olive tree;

don't boast over the branches. But if you boast, it is not you who support the root, but the root supports you.

Again, Isaiah says, "There will be the root of Jesse, he who arises to rule over the Gentiles; in him the Gentiles will hope."
