'Call' in the Bible

Then he ran to Eli and said, "Here I am, for you called me." But Eli said, "I didn't call you. Go back and lie down." So he went back and lay down.

The Lord again called, "Samuel!" So Samuel got up and went to Eli and said, "Here I am, for you called me." But Eli said, "I didn't call you, my son. Go back and lie down."

Is this not the time of the wheat harvest? I will call on the Lord so that he makes it thunder and rain. Realize and see what a great sin you have committed before the Lord by asking for a king for yourselves."
