The root of Jesse refers to the family tree of David and to Jesus Christ, both as descendant and source. It also proclaims that Jesus was thoroughly rooted in our humanity and has become the source of life for us, much as root is to flower. Jesus said, “I am the vine and you are the branches.”

O Root of Jesse, standing as a sign among the peoples;
before you kings will shut their mouths,
to you the nations will make their prayer:
Come and deliver us, and delay no longer.
