1 Samuel 3:16-20

Then Eli called Samuel, and said, Samuel, my son. And he answered, Here am I.

And he said, What is the thing that the Lord hath said unto thee? I pray thee hide it not from me: God do so to thee, and more also, if thou hide any thing from me of all the things that he said unto thee.

And Samuel told him every whit, and hid nothing from him. And he said, It is the LORD: let him do what seemeth him good.

And Samuel grew, and the LORD was with him, and did let none of his words fall to the ground.

And all Israel from Dan even to Beer-sheba knew that Samuel was established to be a prophet of the LORD.
