1 Samuel 3:1-4

Now the boy Samuel was ministering to the LORD before Eli. And word from the LORD was rare in those days, visions were infrequent. It happened at that time as Eli was lying down in his place (now his eyesight had begun to grow dim and he could not see well), and the lamp of God had not yet gone out, and Samuel was lying down in the temple of the LORD where the ark of God was, that the LORD called Samuel; and he said, “Here I am.”
