And Josias begat Jechonias and his brethren--Jeconiah was Josiah's grandson, being the son of Jehoiakim, Josiah's second son (Ch1 3:15); but Jehoiakim might well be sunk in such a catalogue, being a mere puppet in the hands of the king of Egypt (Ch2 36:4). The "brethren" of Jechonias here evidently mean his uncles--the chief of whom, Mattaniah or Zedekiah, who came to the throne (Kg2 24:17), is, in Ch2 36:10, as well as here, called "his brother." about the time they were carried away to Babylon--literally, "of their migration," for the Jews avoided the word "captivity" as too bitter a recollection, and our Evangelist studiously respects the national feeling.
