Yirmeyah 41:7-9

Orthodox Jewish Bible

⁷ And it was so, when they came into the midst of the Ir, that Yishmael ben Netanyah slaughtered them, and cast them into the midst of the cistern, he, and the anashim that were with him.

⁸ But ten anashim were found among them that said unto Yishmael, Slay us not, for we have hidden in the sadeh, chittim, se’orim, shemen, devash. So he forbore, killed them not among the others.

⁹ Now the cistern wherein Yishmael had cast all the pigrei ha’anashim (dead bodies of the men), whom he had slain because of Gedalyah, was the same cistern which Asa HaMelech had made for defense against Ba’asha Melech Yisroel: and Yishmael ben Netanyah filled it with them that were slain.
