1 Samuel 1:11-13

Young's Literal Translation

¹¹ and voweth a vow, and saith, `Jehovah of Hosts, if Thou dost certainly look on the affliction of Thy handmaid, and hast remembered me, and dost not forget Thy handmaid, and hast given to Thy handmaid seed of men -- then I have given him to Jehovah all days of his life, and a razor doth not go up upon his head.'

¹² And it hath been, when she multiplied praying before Jehovah, that Eli is watching her mouth,

¹³ and Hannah, she is speaking to her heart, only her lips are moving, and her voice is not heard, and Eli reckoneth her to be drunken.
