What is the meaning of the word Gethseme?

Gethseme is a garden at the Mount of Olives in Jerusalem.  Its name means “oil press.”  It is the place of agony, the location where Jesus prayed immediately prior to his crucifixion.  Trees in the garden are some of the oldest on earth dating back thousands years and planted from the same parent plant and are capable of growing back even after being cut down to the roots.
