1 Samuel 3:4-6, 8, 16

Then the LORD called Samuel, and Samuel answered, “I am here!” He ran to Eli and said, “I am here. You called me.” But Eli said, “I didn’t call you. Go back to bed.” So Samuel went back to bed. The LORD called again, “Samuel!” Samuel again went to Eli and said, “I am here. You called me.” Again Eli said, “I didn’t call you. Go back to bed.”

The LORD called Samuel for the third time. Samuel got up and went to Eli and said, “I am here. You called me.” Then Eli realized the LORD was calling the boy.

but Eli called to him, “Samuel, my son!” Samuel answered, “I am here.”
