1 Samuel 3:15-20 NIV
Samuel lay down until morning and then opened the doors of the house of the LORD. He was afraid to tell Eli the vision, but Eli called him and said, “Samuel, my son.”
Samuel answered, “Here I am.”
“What was it he said to you?” Eli asked. “Do not hide it from me. May God deal with you, be it ever so severely, if you hide from me anything he told you.” So Samuel told him everything, hiding nothing from him. Then Eli said, “He is the LORD; let him do what is good in his eyes.”
The LORD was with Samuel as he grew up, and he let none of Samuel’s words fall to the ground. And all Israel from Dan to Beersheba recognized that Samuel was attested as a prophet of the LORD.
