John Gill Bible Commentary

And the king said,.... To one of his officers: divide the living child in two; not that he meant it should be actually done, though it might at first be thought he really intended it, and so strike the minds of some with horror, as it did, however, the mother; but he ordered this, to try the affections of the women, and thereby come to the true knowledge of the affair; though, some think he knew it before by their countenances and manner of speech, but that he was desirous all present might see it, and be satisfied of it: and give half to the one, and half to the other; since both claimed it.
