'Olive trees' in the Bible

[to] a land of wheat and barley and vines and fig trees and pomegranate trees, a land of olive trees, olive oil and honey;

When you beat off the fruit of your olive trees you shall not search through the branches afterward, for it shall be for the alien, for the orphan, and for the widow.

There shall be olive trees for you in all of your territory, but you shall not anoint [yourself], for your olives shall drop off.
