Now Hannah was speaking from her heart. Although her lips were moving, her voice was inaudible. Eli therefore thought she was drunk.

When David finished speaking these words to Saul, Saul said, "Is that your voice, my son David?" Then Saul wept loudly.

When Saul recognized David's voice, he said, "Is that your voice, my son David?" David replied, "Yes, it's my voice, my lord the king."
