1 Samuel 1:11-13

1:11 She made a vow saying, “O Lord of hosts, if you will look with compassion on the suffering of your female servant, remembering me and not forgetting your servant, and give a male child to your servant, then I will dedicate him to the Lord all the days of his life. His hair will never be cut.”

1:12 As she continued praying to the Lord, Eli was watching her mouth. 1:13 Now Hannah was speaking from her heart. Although her lips were moving, her voice was inaudible. Eli therefore thought she was drunk.
