1 Samuel 3:8

He arose and went to Eli; he persists in the same readiness to obey and serve him and was not discouraged or driven from his duty by his double mistake and disappointment. Eli perceived, by the consideration of Samuel's piety, of the sanctity of the place adjoining, from whence God had oft-times spoken, and of the solitude of the place, where there was no human person besides himself who could or would have called Samuel in that manner.
