Jeremiah 41:2-7

2Ishmael the son of Nethaniah and the ten men with him rose up and struck down Gedaliah the son of Ahikam, son of Shaphan, with the sword, and killed him, whom the king of Babylon had appointed governor in the land.

3Ishmael also struck down all the Judeans who were with Gedaliah at Mizpah, and the Chaldean soldiers who happened to be there.

4On the day after the murder of Gedaliah, before anyone knew of it,

5eighty men arrived from Shechem and Shiloh and Samaria, with their beards shaved and their clothes torn, and their bodies gashed, bringing grain offerings and incense to present at the temple of the Lord.

6And Ishmael the son of Nethaniah came out from Mizpah to meet them, weeping as he came. As he met them, he said to them, "Come in to Gedaliah the son of Ahikam."

7When they came into the city, Ishmael the son of Nethaniah and the men with him slaughtered them and cast them into a cistern.
