1 Samuel 3:2

¹  And the child Samuel ministered unto the LORD before Eli. And the word of the LORD was precious in those days; there was no open vision.

²  And it came to pass at that time, when Eli was laid down in his place, and his eyes began to wax dim, that he could not see;

³  And ere the lamp of God went out in the temple of the LORD, where the ark of God was, and Samuel was laid down to sleep;

⁴  That the LORD called Samuel: and he answered, Here am I.
