What is the connection between the previous Parshah and the current Parshiyos?
Rashi: Someone who fulfilled the Mitzvah of Shilu'ach ha'Ken will merit to build a new house and fulfill the Mitzvah of Ma'akeh, 1 and ultimately, to plant a vineyard and a field (and have an ox and donkey (and have nice clothes - Da'as Zekenim - with the respective Mitzvos that go with them).
What are the specifications of a "Bayis"?
Sukah, 3b: It is a roof that measures at least four by four Amos (and is ten Tefachim from the ground - Bava Basra, 51a).
Sifri #1: It precludes a guard-hut, a sun-hose and a balcony from the Din of Ma'akeh, which are not considered a Beis-Dirah. 1
Sifri #2: It includes the roof of a palace in the Din of Ma'akeh. 2
Why does the Torah insert the words "Ki Sivneh"?
Sifri: To incorporate a store-house for straw, a stable and a treasury in the Din of Ma'akeh. 1
See Torah Temimah, note 73.
Why does the Torah insert the (otherwise superfluous) phrase "ve'Lo Sasim Damim be'Veisecha"?
Sifri: To extend the Mitzvah of Ma'akeh to a house that is purchased or inherited. 1
Kesuvos, 41b: To ad a La'av against keeping a viscous dog 2 and placing a rickety ladder in the house.
Why does the Torah add the (otherwise superfluous) word "Lo Sasim Damim be'Veisecha"?
Seforno: With reference to 22:8:5:1, it means that the spilt blood should not come from your house.
Sifri: To incorporate pits, trenches, caves, furrow and ditches (that are at least ten Tefachim deep) 1 in the Din of Ma'akeh.
Refer to 22:8:2.5:1.
Why does the Torah insert the (otherwise superfluous) words "Ki Yipol and ha'Nofel mimenu"?
Rashi, Seforno and Targum Yonasan: "ha'Nofel" teaches us that even though he was destined to fall anyway, one should not be the one to cause him to fall, (because Hashem brings about merit through a meritous person and punishments through a guilty one - such as one who did not build a parapet around his roof ? Rashi).
Chulin, 136b: It incorporates a house belonging to partners in the Din of Ma'akeh.
What are the implications of the (otherwise superfluous) word " ? ki Yipol ha'Nofel mimenu"?
Shabbos, 32b #1: To teach us that, since he failed to build a paparet, the onus lies on him to prove that the person who fell did not fall because of him - otherwise he is declared guilty. And by the same token, if someone falls ill, the onus lies on him to prove (to the Heavenly Court) that he is worthy of being healed. Otherwise he is destined to die.
Shabbos, 32a #2: It implies "Mimenu", 've'Lo be'Socho'. Consequently, if one's house is ten Tefachim above street level, he is obligated to build a Ma'akeh, but not if the street is ten Tefachim above his house. 1
See Torah Temimah, note 84.
