1 Kings 17:21 - Joseph Benson’s Commentary on the Old and New Testaments

He stretched himself upon the child three times Not as if he thought this could contribute any warmth or life to the child; but partly to express, and withal to increase, his grief for the child's death, and his desire of its reviving; that thereby his prayers might be more fervent, and consequently more prevalent with God: and partly to give a sign of what God would do by his power, and what he doth by his grace in the raising of souls dead in sin to a spiritual life: the Holy Ghost comes upon them, and the power of the Highest overshadows them, and puts life into them. Let this child's soul come into him again By this way of speaking, Elijah expressed his certainty that the child's soul had left his body, and that he was properly dead. And he asks, not that he might be recovered from a fainting fit, swoon, or trance; but reanimated by the departed soul, and raised from the dead. This certainly was a great and most extraordinary request, and such as there is every reason to think had never been asked of God before by any human creature. Certainly he had no precedent to plead for requesting such a thing, much less did he know of an instance of any mortal's resurrection having taken place in answer to any one's prayers or otherwise. Nevertheless, he was encouraged and induced to make this request, partly by his zeal for God's honour, which he judged was concerned in it, and would be eclipsed, if the child of this widow remained in death; partly by the experience which he had of his prevailing power with God in prayer; and partly by a divine influence, moving him to desire the child's restoration to life.
