John Gill's Exposition of the Whole Bible
1 Chronicles 4:18
And his wife Jehudijah,.... Another wife of Ezra; or, according to Kimchi, of Mered; a Jewess, as the word is by some rendered, to distinguish her from another wife, an Egyptian, in the latter part of the verse:
bare Jered the father of Gedor, and Heber the father of Socho, and Jekuthiel the father of Zanoah; who were princes, as Jarchi seems rightly to observe; of several cities of these names in the tribe of Judah, as of Gedor, see Joshua 15:58, of Socoh, Joshua 15:35, of Zanoah, Joshua 15:34, the Targum interprets the names of all these men of Moses, whom Pharaoh's daughter brought up; and so other Jewish writers a, into which mistake they were led by what follows:
and these are the sons of Bithiah, the daughter of Pharaoh, which Mered took; that is, to wife; this Mered was one of the sons of Ezra, 1 Chronicles 4:17 the Targum, and other Jewish writers b, say this was Caleb, called Mered, because he rebelled against the counsel of the spies; but this contradicts their other notion of Jehudijah, or Bithiah, Pharaoh's daughter, whom he married, the one who brought up Moses, since Moses was elder than Caleb; but Bithiah, whom Mered married, was not a daughter of Pharaoh king of Egypt, but of an Israelite of this name; her sons are supposed to be those in the latter part of 1 Chronicles 4:17.
