Shmuel Alef 7:4-6

Orthodox Jewish Bible

⁴ Then the Bnei Yisroel did put away Baalim and Ashtarot, and served Hashem only.

⁵ And Shmuel said, Gather kol Yisroel to Mitzpah, and I will make intercessory prayer and daven for you unto Hashem.

⁶ And they gathered together at Mitzpah, and drew mayim, and poured it out before Hashem, and did a tzom on that day, and said there, We have sinned against Hashem. And Shmuel judged the Bnei Yisroel at Mitzpah.
