Adam Clarke on 2 Kings 4:35

The child sneezed seven times - That is, it sneezed abundantly. When the nervous influence began to act on the muscular system, before the circulation could be in every part restored, particular muscles, if not the whole body, would be thrown into strong contractions and shiverings, and sternutation or sneezing would be a natural consequence; particularly as obstructions must have taken place in the head and its vessels, because of the disorder of which the child died. Most people, as well as philosophers and physicians, have remarked how beneficial sneezings are to the removal of obstructions in the head. Sternutamenta, says Pliny, Hist. Nat., lib. xxviii., cap. 6, gravedinem capitis emendant; "Sneezing relieves disorders of the head."
