Rashi on Isaiah
says the Master Who possesses everything, and in Whose power it is to uproot you from your land and to settle others in it.
Ibn Ezra on Isaiah
נאום The word of. A noun (comp. Jer. 23:31). To use נֻם instead of נאום is a blunder,44This seems to be an attack on those Paytanim who use נם instead of נאם, with omission of א. But in his Moznaim, a grammatical pamphlet, the author adduces several instances in which א is omitted. (See Moznaim sub voce נעל ים). for א cannot be omitted.
