1 Kings 17:22 - Joseph Benson’s Commentary on the Old and New Testaments

The soul of the child came into him again The reader will easily observe, that this phraseology of the sacred historian, like that of the prophet in the former verse, (and they both spoke by inspiration of God,) plainly signifies the distinction between the rational soul and earthly body to be as real as that between the house and its inhabitant, and supposes the existence of the former in a state of separation from the body, and consequently its immortality: and, probably, as Grotius thinks, God might design by this miracle to give an evidence hereof for the encouragement of his suffering people. And he revived As by an extraordinary and supernatural stroke of affliction, God had taken away the child's life for the trial of the faith, both of the prophet and the woman; so, to strengthen the faith of both, as well as for the vindication of the true religion, and the manifestation of his own glory in opposition to idols, in that most dark and degenerate age, he restored the child to life, and thereby answered the prayer which he himself had inspired.
