'Rashi': This is Kalev's wife. She was born from Yehudis.

Radak (17-18) She was Mered's wife. We infer that his first wife was not a Yehudiyah, rather, Bisyah, like it says below.

Malbim: This is Kalev's third wife. Her name was ha'Yehudiyah. I mentioned (2:52) that many names begin with Hei.

'Rashi': They are the officers of these cities. These cities are mentioned in Yehoshua (15:56) "v'Yakde'am v'Zanu'ach Chalchul Beis Tzur u'Gedor? Shocho."

Radak: The verse lists the names of the sons. The fathers are mentioned for publicity, when the son was honored and known via his father.

Radak citing Chazal: All these names Avigdor, Chever? are expounded about Moshe. It says that Bisyah gave birth to him, for she raised him.

'Rashi': The prefix Vov in v'Eleh distinguishes sons of Yehudiyah (mentioned above) from Bisyah's son. It says Bnei, even though only one is listed ¹ .

Radak: These are those mentioned first, before it mentions his Jewish wife.

Malbim: She was Kalev's fourth wife. We do not know if Pharaoh is a Yisrael, or Melech Mitzrayim (Megilah 13a). Her sons were Mered, and those in the coming verse.

'Rashi': This is Kalev, who Marad (rebelled) against the Meraglim's counsel (Sanhedrin 19b).

Radak: Yes. Mered was Ben Ezrah (17), from Bnei Kalev ben Yefuneh.

Malbim: No - Kalev married her; Mered was their son ¹ .
