The first pressing releases virgin olive oil, though some people say that virgin oil is what spontaneously comes out of the baskts even before pressing. At any rate, this is the cold press method. The virgin oil was used for the Menorah in the Temple.
Olive oil is used also for anointing, from which the work MESCHIACH and in Greek Christos. If Israel used to be famous for Jaffa oranges, it is now famous for olive oil. In fact, the symbol of Israel is the Olive Tree: the orange originates in China and came to the Middle East through India.
The olive is also a symbol of peace: the dove brought back a branch of an olive tree to Noah. Why would it bring an olive branch and not a date palm leaf? Because the olive tree is much smaller, and would indicate better the receding of the waters. Also because the dove – and anyone – would rather eat bitter fruit in freedom than sweet [date] fruit in captivity. So the olive is also a symbol of freedom.
The Menorah is mentioned in Zechariah. “Not by might, not by force, but by the Spirit.” The Menorah is not so much for giving light; it represents the Spirit. It may be seen on Titus’ Arch in the Roman Forum, where the Jewish slaves are shown carrying it, a sign therefore of humiliation. The only time the Romans minted a coin commemorating the defeat of a people was upon the capitulation of Judea: Judea Capta. The State of Israel turned the Menorah into a symbol of victory, and coined a medallion depicting a man carrying a baby and a woman planting a tree: Judea Liberata. During the compulsory military training, the young people are given a rifle and a bible, and they are read this verse from Zechariah: Not by might, not by force, but by the Spirit.” Emanuele De Maria made a connection with Don Bosco’s dream at the age of 9: “not by blows, but with kindness will you gain them.”
