'Olive trees' in the Bible

And houses full of all good things, which you filled not, and wells dug, which you dug not, vineyards and olive trees, which you planted not; when you shall have eaten and be full;

You shall have olive trees throughout all your borders, but you shall not anoint yourself with the oil; for your olives shall drop off.

And over the olive trees and the sycamore trees that were in the lowlands was Baal-hanan the Gederite: and over the stores of oil was Joash:

I have smitten you with blight and mildew: when your gardens and your vineyards and your fig trees and your olive trees increased, the locust devoured them: yet have you not returned unto me, says the LORD.

And two olive trees by it, one upon the right side of the bowl, and the other upon its left side.

Then answered I, and said unto him, What are these two olive trees upon the right side of the lampstand and upon its left side?

These are the two olive trees, and the two lampstands standing before the God of the earth.
