He sent his word, and healed them, and delivered them from their destructions.
He sent his word, and healed them. "His word" is His swift and omnipotent instrument sent forth to do His bidding. So the centurion's faith viewed the word of Jesus (Matthew 8:8: cf. Psalms 147:15; Psalms 147:18).
And delivered them from their destructions - literally, from their pits; Psalms 107:18, "the gates of death." Compare Lamentations 4:20; Isaiah 38:10; Psalms 103:4. The Psalmist probably had in view Job 33:28.
