He sent his word, and healed them,.... It was his will and pleasure they should be healed, and accordingly they were; he issued his orders for the removal of the affliction, and it was done; diseases are his servants, which come and go at his command; so Christ, in the days of his flesh, healed by speaking a word, Mt 8:3.
This is true of Christ the essential Word, who was sent in the fulness of time, and was made flesh and dwelt among men, and went about healing all manner of diseases among the people; and who is also the physician of souls who came with healing in his wings; that is, with pardon of sin, for which his blood was shed: he is the only physician, the skilful, universal, and infallible one, and does all freely, and in a most marvellous manner, by his stripes, blood and wounds, and by an application of these to diseased persons sensible of their case.
It may also be applied to the word of the Gospel; the law is the means of wounding, it is the killing letter; the Gospel is the means of healing, the doctrines of it are the leaves of the tree of life, which are for the healing of the nations; it is the doctrine of remission of sins by the blood of Christ, and by it Christ speaks peace and pardon to wounded consciences.
