Jechonias begat Salathiel (Shealtiel, Revised Version). From Jeremiah 22:30 it has sometimes been thought that Jechoniah died childless, though the preceding context, which speaks of him and his seed, seems hardly to warrant the supposition; but clearly the words of the prophet there imply that none of his descendants should attain to a position such as was held by Zerubbabel, and that his family should soon come to an end.
If we look at the genealogy in 1 Chronicles 3:17 we find Assir mentioned as the son of Jechoniah (cf., however, Revised Version, "Jeconiah the captive"), and Salathiel as his son; and in the next verse Pedaiah, a brother of Salathiel, is named as father of Zerubbabel.
By St. Luke (Luke 3:27) Salathiel is called the son of Neri, and in Ezra 3:2; Ezra 5:2; and Haggai 1:1 Zerubbabel is called the son of Shealtiel. These are all the details we have, and to decide on how they are related to each other is very difficult.
We.may, perhaps, be right in supposing that Pedaiah, the brother of Shealtiel, having died, his son Zerubbabel was adopted by Shealtiel. We must then suppose that, the royal line through Solomon having ended, and Jechoniah's only child, Assir (if he ever existed, vide supra), having left no issue, the line of David is taken up through the family of the other son, Nathan, and that from him descended Neri, the father of Shealtiel, who takes the place of Jechoniah's issue, which has altogether failed.
