'Olive branches' in the Bible

And so they caused it be declared and proclaimed in all their cities, and at Jerusalem, saying, "Go up unto the mount and fetch Olive branches, and Pine branches, Myrtle branches, Palm branches, and branches of thick trees, to make booths, as it is written."

Thy wife shall be as the fruitful vine upon the walls of thy house, thy children like the olive branches round about thy table.

I spake moreover, and said unto him, 'What be these two olive branches which, through the two golden pipes, empty themselves into the gold?'

Then said he, 'These are the two olive branches that stand before the ruler of the whole earth.'
