Kabbalah do Izajasza 41:27

Come and see, Aleph on its own is called first, which is male; for the unknown is hidden and concealed in Aleph. When this Aleph is connected to another place, that place is called beginning. You might say it is connected – no, it appears in it and shines in it. Then it is called beginning. Even that beginning (spelled with Aleph) does not watch over Jerusalem; had Jerusalem received from this beginning, it would be constantly alight, and its union would not be intermittent. However, it is spelled reshit without Aleph, and so its union is intermittent. In the world to come it is written, “A first of Zion will I give” (Yeshayahu 41:27). Aleph that is called first will shine upon Zion that is Malchut.
