'Shaking' in the Bible

Yet there shall be left therein gleanings, as the shaking of an olive-tree, two or three berries in the top of the uppermost bough, four or five in the outmost branches of a fruitful tree, saith Jehovah, the God of Israel.

In that day shall the Egyptians be like unto women; and they shall tremble and fear because of the shaking of the hand of Jehovah of hosts, which he shaketh over them.

For thus shall it be in the midst of the earth among the peoples, as the shaking of an olive-tree, as the gleanings when the vintage is done.
