Why does it say "Ki"?
Radak: Nine and a half Shevatim received via the lottery, even though Levi did not receive, because Yosef counted as two.
Why does it repeat "like Hashem commanded"? Also verse 2 said so!
Malbim: Also other details were like Hashem commanded, e.g. "la'Rav Tarbeh Nachalaso."
What are Mikneihem and Kinyanam?
Radak citing Targum Yonasan: They are their big (work) animals and small animals, respectively.
