What is the meaning of "v'Sham Nikra"?
Rashi: Was summonsed there. This is like "Hikdish Keru'av" (Tzefanyah 1:7), "va'Yikra Avshalom l'Chol Bnei ha'Melech" (13:23).
Malbim: In the place of the quarrel between Yehudah and Yisrael (Yehudah said that they are the primary kingship, for he is from their Shevet), there chanced to be this evil person.
What is the meaning of "Beliya'al"?
Malbim: He arouses quarrels.
Why did he say "Ein Lanu Chelek b'David"?
Malbim: David pertains to his Shevet. The other Shevatim have no share in him. Yehudah refuted Yisrael's claim that they have 10 shares in him.
Why did he add "v'Lo Nachalah b'Ven Yishai"?
Malbim: One becomes king if all want him, or if his father was king; kingship is hereditary. Also the latter he does not have. His father Yishai was a commoner!
