Who were "Nikevu b'Shemos"?
'Rashi': Those listed above - Kananyah and his brothers, who were appointed to receive Terumos and Ma'aseros from Yisrael, and give them to Kohanim and Leviyim.
Malbim: They are people in each city who were appointed to divide portions among Kohanim not serving in the Mikdash.
Did they give only to the male Kohanim?
'Rashi': They gave also for the wives and daughters. It says Zecharim, for we give portions for males from the age of three, and all the more so for wives, and sons and daughters 1 !
Radak: This refers to portions proper for males 2 .
Malbim: For males who served in the Mikdash, they did not need Lehisyaches (show their lineage). We do not check the lineage of one who served on the Mizbe'ach, or his ancestors (surely they checked before letting him serve)! Refer to 31:19:3:2.
What is the meaning of "ul'Chol Hisyaches ba'Leviyim"?
Redak: This refers to their wives and children.
Malbim: Leviyim needed to show their lineage; they do not serve on the Mizbe'ach.
