“But the Angel said vnto him, Feare not, Zacharias, for thy prayer is heard, and thy wife Elizabeth shall beare thee a sonne, and thou shalt call his name Iohn.”
1611 King James Version (KJV)
1:13 Thy prayer is heard - Let us observe with pleasure, that the prayers of pious worshippers come up with acceptance before God; to whom no costly perfume is so sweet, as the fragrancy of an upright heart. An answer of peace was here returned, when the case seemed to be most helpless. Let us wait patiently for the Lord, and leave to his own wisdom the time and manner wherein he will appear for us. Thou shalt call his name John - John signifies the grace or favour of Jehovah. A name well suiting the person, who was afterward so highly in favour with God, and endued with abundance of grace; and who opened a way to the most glorious dispensation of grace in the Messiah's kingdom. And so Zacharias's former prayers for a child, and the prayer which he, as the representative of the people, was probably offering at this very time, for the appearing of the Messiah, were remarkably answered in the birth of his forerunner.
Lu 1:13 Fear not. This first celestial message at the dawning of the New Testament dispensation is one of cheer. Thy prayer is heard. The childless old priest had prayed for offspring. Shalt call his name John. That is, "the God-given".
