Shmuel Alef 7:10-12

Orthodox Jewish Bible

¹⁰ And as Shmuel was offering up the olah, the Pelishtim drew near to battle against Yisroel; but Hashem thundered with a kol gadol on that day upon the Pelishtim, and threw them into confusion and panic; and they were struck down before Yisroel.

¹¹ And the Anshei Yisroel went from Mitzpah, and pursued the Pelishtim, and struck them down, until they came to below Beit-Kar.

¹² Then Shmuel took one even (stone), and set it up between Mitzpah and Shen, and called the shem of it Even-Ezer, saying, Hitherto hath Hashem helped us.
