Gemara Sotah 2a
אמר רב יהודה אמר רב ארבעים יום קודם יצירת הולד בת קול יוצאת ואומרת בת פלוני לפלוני בית פלוני לפלוני שדה פלוני לפלוני...
Rav Yehuda says that Rav says: Forty days before an embryo is formed a Divine Voice issues forth and says: The daughter of so-and-so is destined to marry so-and-so; such and such a house is destined to be inhabited by so-and-so; such and such a field is destined to be farmed by so-and-so.
What is specific about the pre-ordination of these 3 things (spouses, houses, and fields)? Are other things less preordained? If so in what way are these three different?
