1 Samuel 3:6-8

King James Version

⁶ And the Lord called yet again, Samuel. And Samuel arose and went to Eli, and said, Here am I; for thou didst call me. And he answered, I called not, my son; lie down again.

⁷ Now Samuel did not yet know the Lord, neither was the word of the Lord yet revealed unto him.

⁸ And the Lord called Samuel again the third time. And he arose and went to Eli, and said, Here am I; for thou didst call me. And Eli perceived that the Lord had called the child.
