Shemini: The Conclusion of the Installation Rites; Kashrut

For the land into which you are entering, to inherit it, is not like the land of Egypt from which you are coming, that you sow your seed and water it with your feet like a vegetable garden. The land into which you are crossing to inherit is a land of hills and valleys, which drinks water of the rain of the heavens. A land which the L-rd your G-d seeks; constantly the eyes of the L-rd your G-d are on it, from the beginning of the year to the end of the year.

  –Deuteronomy 11:10-12
