1 Samuel 3:4 WEB

²  It happened at that time, when Eli was laid down in his place (now his eyes had begun to grow dim, so that he could not see),

³  and the lamp of God hadn't yet gone out, and Samuel had laid down [to sleep], in the temple of Yahweh, where the ark of God was;

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.
