1 Samuel 3:9-11

King James Version

⁹ Therefore Eli said unto Samuel, Go, lie down: and it shall be, if he call thee, that thou shalt say, Speak, Lord; for thy servant heareth. So Samuel went and lay down in his place.

¹⁰ And the Lord came, and stood, and called as at other times, Samuel, Samuel. Then Samuel answered, Speak; for thy servant heareth.

¹¹ And the Lord said to Samuel, Behold, I will do a thing in Israel, at which both the ears of every one that heareth it shall tingle.
