The tree has always symbolized life and spirituality
and so does the 8th century CE "Tree of Life" Mosaic
discovered in Hisham's Palace near Jericho. The Tree
of Life is also a central symbol in the Kabbalah - the
Jewish mystical world.
Jacob dreams of a ladder, upon which angels go
up and down. The ladder is an important symbol in
the Kabbalah, representing a means for a person to
elevate his soul to higher spiritual levels.
