1 Samuel 3:6-8

New King James Version

⁶ Then the Lord called yet again, “Samuel!”

So Samuel arose and went to Eli, and said, “Here I am, for you called me.” He answered, “I did not call, my son; lie down again.” ⁷ (Now Samuel ^(A)did not yet know the Lord, nor was the word of the Lord yet revealed to him.)

⁸ And the Lord called Samuel again the third time. So he arose and went to Eli, and said, “Here I am, for you did call me.”

Then Eli perceived that the Lord had called the boy.
