Yeremia 40:14

40:14 They said to him, “Are you at all aware ¹  that King Baalis of Ammon has sent Ishmael son of Nethaniah to kill you?” But Gedaliah son of Ahikam would not believe them.

Yeremia 41:1-2

41:1 But in the seventh month ²  Ishmael, the son of Nethaniah and grandson of Elishama who was a member of the royal family and had been one of Zedekiah’s chief officers, came with ten of his men to Gedaliah son of Ahikam at Mizpah. While they were eating a meal together with him there at Mizpah, 41:2 Ishmael son of Nethaniah and the ten men who were with him stood up, pulled out their swords, and killed Gedaliah, the son of Ahikam and grandson of Shaphan. Thus Ishmael killed the man that the king of Babylon had appointed to govern the country.

[40:14]  ¹ tn The translation is intended to reflect the emphasizing infinitive absolute before the finite verb.

[41:1]  ² sn It is not altogether clear whether this is in the same year that Jerusalem fell or not. The wall was breached in the fourth month (= early July; 39:2) and Nebuzaradan came and burned the palace, the temple, and many of the houses and tore down the wall in the fifth month (= early August; 52:12). That would have left time between the fifth month and the seventh month (October) to gather in the harvest of grapes, dates and figs, and olives (40:12). However, many commentators feel that too much activity takes place in too short a time for this to have been in the same year and posit that it happened the following year or even five years later when a further deportation took place, possibly in retaliation for the murder of Gedaliah and the Babylonian garrison at Mizpah (52:30). The assassination of Gedaliah had momentous consequences and was commemorated in one of the post exilic fast days lamenting the fall of Jerusalem (Zech 8:19).
