Rashi on Isaiah
Even [as though] they were not planted They are even as though they were not planted.
Ibn Ezra on Isaiah
Yea, they shall not be planted, etc. They shall be like trees, that perished as completely as if they had never been planted. נטעו is Niphal; זרעו is Pual;
Rashi on Isaiah
even [as though] they were not sown And still more than this, that they shall be uprooted and plucked out, as if they were not sown. Sowing is less than planting.
