1 Samuel 3:6 WEB

⁴  that Yahweh called Samuel; and he said, Here am I.

⁵  He ran to Eli, and said, Here am I; for you called me. He said, I didn't call; lie down again. He went and lay down.

⁶  Yahweh called yet again, Samuel. Samuel arose and went to Eli, and said, Here am I; for you called me. He answered, I didn't call, my son; lie down again.

⁷  Now Samuel didn't yet know Yahweh, neither was the word of Yahweh yet revealed to him.

⁸  Yahweh called Samuel again the third time. He arose and went to Eli, and said, Here am I; for you called me. Eli perceived that Yahweh had called the child.
