The Olive Leaf – the Dove Carrying Peace in her Mouth
The origin of the ‘dove and olive leaf’ as a symbol of peace
The adoption of this image of the dove and olive leaf as a symbol of peace owes to the fact that, by returning with the olive leaf in its mouth, the dove signalled to Noah that the Flood was over and the waters had already mostly receded. Since olive trees do not grow tall but remain closer to the ground than other trees, Noah understood that the floodwaters were already drying up, since the dove could already access an olive leaf. The receding of the floodwaters indicated that the time of HaShem’s wrath against mankind had passed.
Thus the twin motif of the dove and the olive leaf together are used in the modern world to represent peace and tranquillity. The olive leaf has been incorporated into one of the symbols of the state of Israel, as an expression of the aspiration and hope of its people to live in peace and tranquillity upon its land.
