ועץ השדה יתן פריו… (בחקותי כו:ד)

The Gemara (Kesubos 112:2) says that in the time of Moshiach, the barren tree will start bearing fruit, as it says in our Parasha: “ועץ השדה יתן פריו”.  This could be the deeper meaning of the prayer when we bless the new moon:  ”ויקבץ נדחנו מארבע כנפות הארץ חברים כל ישראל” (And He shall gather our exiled from the four corners of the world – all Yidden are friends): the word “Chaverim” can also be translated as “a learned man” – a Talmid Chacham, thus: with the coming of Moshiach we will all become Chaverim, who will learn the Torah and author Chidushei Torah (Torah innovations).  Sefas Emes
