Es bleiben nur wenige übrig wie die Beeren zur Nachlese, wie beim Olivenschlagen, zwei, drei Beeren an der Spitze des Wipfels, vier, fünf an ihren fruchtreichen Ästen, — ist der Spruch des Herrn, des Gottes Israels.
Rashi on Isaiah
And...shall be left in it Hezekiah and his company, who are inside Jerusalem. They are few people like the gleanings of a vineyard and like the cutter of an olive tree, who leaves over two or three berries.
Ibn Ezra on Isaiah
כנוקף As the shaking of. Comp. ונקף and he will cut down (10:34); ינקופו let them kill (29:1).
Rashi on Isaiah
like the cutter of an olive tree Heb. כְּנֹקֶף, like the one who cuts olives to pick them from the tree. Comp. (infra 10:34) “And the thickets of the forest shall be cut off (וְנִקַּף).” Our Rabbis expounded: “And...shall be left in it,” as referring to Sennacherib’s army; i.e., there shall be left in the multitude of Sennacherib a few people like the cutter of an olive tree, as it is stated in the Aggadah of ‘Chelek’ (95b).
