'Root' in the Bible

If the first part of the dough is holy, so is the whole batch. If the root is holy, so are the branches.

Now if some of the branches have been broken off, and you, a wild olive branch, have been grafted in their place to share the rich root of the olive tree,

do not boast about being better than the other branches. If you boast, remember that you do not support the root, but the root supports you.

And again, Isaiah says, "There will be a Root from Jesse. He will rise up to rule the gentiles, and the gentiles will hope in him."
