Shmuel Alef 1:11-13

Orthodox Jewish Bible

¹¹ And she vowed a neder (vow), and said, O Hashem Tzva’os, if thou wilt indeed look on the misery of thine handmaid, and remember me, and not forget thine handmaid, but wilt give unto thine handmaid zera anashim, then I will give him unto Hashem kol yamei of his chayyah, and there shall no razor come upon his head.

¹² And it came to pass, as she continued davening before Hashem, that Eli observed her mouth.

¹³ Now Channah, she davened in her lev; only her lips moved, but her voice was not heard; therefore Eli thought her to be shikkorah.
