Yeremia 40:15

40:15 Then Johanan son of Kareah spoke privately to Gedaliah there at Mizpah, “Let me go and kill Ishmael the son of Nethaniah before anyone knows about it. Otherwise he will kill you ¹  and all the Judeans who have rallied around you will be scattered. Then what remains of Judah will disappear.”

Yeremia 41:3

41:3 Ishmael also killed all the Judeans ²  who were with Gedaliah at Mizpah and the Babylonian ³  soldiers who happened to be there. ⁴ 

[40:15]  ¹ tn Heb “Why should he kill you?” However, this is one of those cases listed in BDB 554 s.v. מָה 4.d(b) where it introduces a question introducing rhetorically the reason why something should not be done. In cases like this BDB notes that it approximates the meaning “lest” and is translated in Greek by μήποτε (mhpote) or μή (mh) as the Greek version does here. Hence it is separated from the preceding and translated “otherwise” for the sake of English style.

[41:3]  ² sn All the Judeans. This can scarcely refer to all the Judeans who had rallied around Gedaliah at Mizpah because v. 10 later speaks of Ishmael carrying off “the rest of the people who were at Mizpah.” Probably what is meant is “all the Judeans and Babylonian soldiers” that were also at the meal. It is possible that this meal was intended to seal a covenant between Gedaliah and Ishmael of Ishmael’s allegiance to Gedaliah and his Babylonian overlords (cf. Gen 26:30-31; 31:53-54; Exod 24:11). In any case, this act of treachery and deceit was an extreme violation of the customs of hospitality practiced in the ancient Near East.

[41:3]  ³ tn Heb “Chaldean.” See the study note on 21:4 for explanation. There are two cases of apposition with the repetition of the preposition or of the sign of the accusative in this verse, e.g., “who were with him, [namely] with Gedaliah” and “all the Chaldeans who happened to be there, [namely] the soldiers.”

[41:3]  ⁴ tn Heb “were found there.” For this nuance of the verb see BDB 594 s.v. מָצָא Niph.2.c.
