'I Am He' in the Bible

And the LORD called once again, "Samuel." And Samuel arose and went to Eli and said, "I am here, thou didst call me." And he answered, "I called thee not my son. Go again and take thy rest."

And the LORD went and called Samuel the third time. And he arose and went to Eli and said, "I am here, for thou hast called me." Then Eli perceived that the LORD had called the lad.

And the man said unto Eli, "I am he that came out of the array and fled out of the host this day." And he said, "How is it fortuned, my son?"
