Charles Ellicott Commentary 2 Kings 24:8

"Jehoiachin was eighteen years old when he began to reign; and he reigned in Jerusalem three months: and his mother`s name was Nehushta the daughter of Elnathan of Jerusalem." — 2 Kings 24:8 (ASV)

THE REIGN OF JEHOIACHIN. BEGINNING OF THE BABYLONIAN CAPTIVITY
(2 Kings 24:8–16).

Jehoiachin. —“Jah will confirm.” Four or five different forms of this name occur in the documents. Ezekiel 1:2 gives the contraction Joiachin. In Jeremiah we find a popular transposition of the two elements, thus: Jechonjahu (once, namely, Jeremiah 24:1, Heb.), and usually the shorter form, Jechoniah (Jeremiah 27:20; Esther 2:6); which is further abridged into Coniah (Heb., Chonjahu) in Jeremiah 22:24; Jeremiah 22:28. Ewald thinks this last the original name; but Hengstenberg supposes that the prophet altered the name, so as to make of it a “Jah will confirm” without the “will,” in order to foreshadow the fate which awaited this king.

Nehushta. —Referring, perhaps, to her complexion (as we say “bronzed”).

Elnathan. —See Jeremiah 26:22; Jeremiah 36:12; Jeremiah 36:25; one of Jehoiakim’s “princes.”
