'Olive trees' in the Bible

And [there are] two olive trees by it, one on the right of the bowl and the other on its left."

And I answered and said to him, "What [are] these two olive trees on the right of the lampstand and on its left?"

And I replied a second [time] and asked him, "What [are] these two twigs of olive trees on the right of the lampstand and on its left?"
