Why did he say "who is David and who is Ben Yishai"?
Rashi: Of what importance is he? He comes from Rus ha'Mo'aviyah!
Kli Yakar: Who says that David really sent you? He is esteemed - would he send to request food?!
Malbim: He is not important himself, not from his fathers. He is known only for rebelling against the king.
What is the meaning of "ha'Yom Rabu Avadim ha'Mispartzim"?
Radak: Now many flee from and rebel against their masters.
Kli Yakar citing Mahari: I would be willing to give to David himself. Should I give to 600 men?!
Kli Yakar: Perhaps David did not send you, and you falsely claim that he did. Nowadays, many are brazen to their masters!
Malbim: Previously, this would be a Chidush. Nowadays that many rebel, David is not famous even for his rebellion!
