Bamidbar 26:13

לזרח OF ZERAH — He is identical with Zohar (mentioned in Exodus 6:15 as a son of Simeon), which is an expression equivalent to צהר, shining (a synonym of זרח). However, the family of אהוד (mentioned there) had ceased to exist by now. The same was the case with five families of the tribe of Benjamin, for with ten sons did Benjamin go down to Egypt and here it enumerates only five. Similarly with Ezbon of the tribe of Gad. So you have seven families that had become extinct (cf. Midrash Tanchuma, Pinchas 5). — And I have found in the Talmud Yerushalmi Yoma 1:2 the reason why these seven families were now extinct: that when Aaron died the clouds of glory departed and the Canaanites came to wage war against Israel. These therefore set their hearts on returning to Egypt and turned back eight stages from Mount Hor to Moserah, as it is said, (Deuteronomy 10:6) “And the children of Israel journeyed from Bene Jaakon to Moserah; there Aaron died”. But did he not die at Mount Hor and from Moserah to Mount Hor there were eight stages in a backward direction? But the explanation is that they turned back, and the Levites pursued them to force them to return and slew of them seven families. And besides these, of the sons of Levi there fell four families: the families of Shimei and Uzzieli, and of the three sons of Izhar (Exodus 6:21) only the family of one son, Korah, is enumerated here, v. 58, so that the family of Izhar may be regarded as extinct — making three families missing. And as regards the fourth family I do not know which of those mentioned in 3:21, 27, 33, it was that had become extinct by now (Talmud Yerushalmi Sotah 1:10; Yoma 1:1). But Rabbi Tanchuma (Midrash Tanchuma, Pinchas 5) explained that they (the families not mentioned here) died by the plague in the matter of Balaam. But this can hardly be so, because according to the deficiency that shows itself in the tribe of Simeon in this census, as compared with the first census in the wilderness of Sinai (1:23), it would appear that all the twenty four thousand who died of that plague (Numbers 25:9) must have fallen from the tribe of Simeon.

of Zeraĥ, the family of the Zarĥi: of Sha᾽ul, the family of the Sha᾽uli.
