King James Bible
"And his mouth was opened immediately, and his tongue loosed, and he spake, and praised God."
Zechariah's nine months of divinely imposed muteness ends the instant he obeys by naming his son John. The physical restoration of speech confirms God's promise fulfilled and demonstrates that his earlier doubt has been replaced by faith. Zechariah's first words after regaining speech are directed toward God in worship, not explanation to the crowd. This immediate praise reveals a transformed heart and sets the pattern for his prophetic song that follows, showing that encounters with God's faithfulness naturally overflow in worship.
