24. As I live--God's most solemn formula of oath (Jer 46:18; 4:2; De 32:40; 1Sa 25:34).
      Coniah--Jeconiah or Jehoiachin. The contraction of the name is meant in contempt.
      signet--Such ring seals were often of the greatest value (So 8:6; Hag 2:23). Jehoiachin's popularity is probably here referred to.
      right hand--the hand most valued.
      I would pluck thee thence--(Compare Ob 4); on account of thy father's sins, as well as thine own (2Ch 36:9). There is a change here, as often in Hebrew poetry, from the third to the second person, to bring the threat more directly home to him. After a three months' and ten days' reign, the Chaldees deposed him. In Babylon, however, by God's favor he was ultimately treated more kindly than other royal captives (Jer 52:31-34). But none of his direct posterity ever came to the throne.
