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.
