When in the seventh month was this?
Radak: It was on Rosh Chodesh (i.e. Rosh Hashanah), like "Machar Chodesh" (Shmuel I, 20:18). Gedalyah was killed on Rosh Hashanah, but the fast over his death was fixed for the day after Rosh Hashanah, for it is Yom Tov (so we may not fast).
What is "mi'Zera ha'Meluchah"?
Radak: He was from Beis David. He was jealous that Gedalyah was appointed over the land.
Radak (from Yerushalmi Sanhedrin 2:3): He descended from converts, for Yerachmi'el married Atarah, like it says in Divrei ha'Yamim (I, 2:26); she was a Nochris princess. He married her to aggrandize himself - therefore she is called Atarah. va'Tehi Ishah Acheres li'Yrachmi'el u'Shmah Atarah Hi Em Ones" - she entered mourning into his house. Do not trust a convert for 24 generations (Yalkut Shimoni Rus 601); Yishmael was the 24th generation from Atarah. 1
Divrei ha'Yamim I, 2:26-41 lists generations from Atarah until Elishama. Radak (I, 2:26) is Mechadesh that that Elishama was Yishmael's grandfather, and how the count of generations is 24. (PF)
Who are "Rabei ha'Melech"?
