Charles Ellicott Commentary Matthew 1:11

"and Josiah begat Jechoniah and his brethren, at the time of the carrying away to Babylon." — Matthew 1:11 (ASV)

Jechonias and his brethren — Here again there is a missing link in the name of Eliakim, or Jehoiakim, the son of Josiah (2 Kings 23:34). Jechonias was therefore the grandson of Josiah. The alternative reading mentioned in the margin rests on very slight authority and was obviously the insertion of some later scribe to meet the difficulty. The word “brethren” was probably meant to include Mattaniah or Zedekiah, the last king of Judah, who was the son of Josiah and therefore uncle to Jechonias.
