Jeremiah 40:14

Dost thou certainly know that Baalis... — The king of the Ammonites so named appears from Jeremiah 27:3 to have been in alliance with Zedekiah; and Ishmael, as belonging to the royal house of Judah, seems to have been still plotting with him against the authority of the Chaldæans. Open resistance being now impossible, they have recourse to assassination. The plot becomes known, and Johanan, faithful to his new protector, warns him against it, but, as the sequel shows, in vain. Gedaliah, in the guileless trustfulness of his character, does not believe that Ishmael is capable of such a crime, and will not sanction another crime by way of precaution.
