He sent his word, and healed them - He did it by a word; it was necessary for him merely to give a command, and the disease left them. So it was in the life of the Saviour, who often healed the sick by a “word” Matthew 8:8; Luke 7:7; and so now restoration from disease often seems to be accomplished as if some word had been spoken by one who had power, commanding the disease to depart. In all cases, also, whatever means may be used, healing power comes from God, and is under his control. Compare Psalms 30:2.
And delivered them from their destructions - From what would have destroyed them, if it had not been checked and removed.
