C. F. Keil and Franz Delitzsch on Jeremiah 41:6-7

Jer 41:6-7

Ishmael went out from Mizpah to meet these men, always weeping as he went (הלך הלך וּבכה, cf. Ges. §131, ab; Ew. §280, b). If they came from Ephraim by way of Gibeon (el Jîb), the road on to Jerusalem passed close by Mizpah. When Ishmael met them, he asked them to come to Gedaliah (to Mizpah). But when they had entered the city, "Ishmael slew them into the midst of the pit" (which was there), i.e., killed them and cast their corpses into the pit.
