Charles Ellicott Commentary Jeremiah 29:2

"(after that Jeconiah the king, and the queen-mother, and the eunuchs, [and] the princes of Judah and Jerusalem, and the craftsmen, and the smiths, were departed from Jerusalem,)" — Jeremiah 29:2 (ASV)

The queen. —This was probably the queen-mother, Nehushta, the daughter of Elnathan (2 Kings 24:8). The name probably indicates a connection with the Elnathan, the son of Achbor, of Jeremiah 26:22, but we cannot assert with any confidence that these two were the same person.

The carpenters, and the smiths. —See Note on Jeremiah 24:1. Among the exiles thus referred to as “princes” we have to think of Daniel, and those who are best known to us by their Babylonian names as Shadrach, Meshach, and Abed-nego (Daniel 1:6–7). The conduct, we may well believe, was in accordance with Jeremiah’s teaching.
