John Gill, on Luke 1:64

“And immediately his mouth was opened, and his tongue loosed, and he spoke, blessing God.”

“And his mouth was opened immediately,.... As soon as ever the child was named, and so all things accomplished which the angel had foretold, and his tongue loosed; the impediments of speech were removed, and the use of his tongue and lips was restored unto him: and he spake and praised God; for the safe delivery of his wife; for the birth of his son, the forerunner of Christ; for the conception of the Messiah; for God's gracious regards to his church and people, in these instances; and for the restoration of speech and hearing to himself, of which he had been some time deprived for his unbelief.”
