1 Samuel 3:4-5, 10

Then GOD called out, “Samuel, Samuel!” Samuel answered, “Yes? I’m here.” Then he ran to Eli saying, “I heard you call. Here I am.” Eli said, “I didn’t call you. Go back to bed.” And so he did.

Then GOD came and stood before him exactly as before, calling out, “Samuel! Samuel!” Samuel answered, “Speak. I’m your servant, ready to listen.”
