Jeremiah 41:4

Then arose Ishmael the son of Nethaniah, and the ten men who were with him, and struck Gedaliah the son of Ahikam the son of Shaphan with the sword, and killed him, whom the king of Babylon had made governor over the land.

Ishmael also killed all the Jews who were with him, [to wit], with Gedaliah, at Mizpah, and the Chaldeans who were found there, the men of war.

that there came men from Shechem, from Shiloh, and from Samaria, even eighty men, having their beards shaved and their clothes torn, and having cut themselves, with meal offerings and frankincense in their hand, to bring them to the house of Yahweh.

Ishmael the son of Nethaniah went forth from Mizpah to meet them, weeping all along as he went: and it happened, as he met them, he said to them, Come to Gedaliah the son of Ahikam.
