Before God - In the temple, where God dwelt by the symbols of His presence. The temple was regarded by the Jews as the "house" or dwelling of God; and in the "first" temple there was, in the most holy place, a "cloud" called the Shechinah, or a visible sign of the presence of God. It was thus "before God" that Zechariah offered incense.

Before God - In the temple, where God used to manifest his presence, though long before this time he had forsaken it; yet, on this important occasion, the angel of his presence had visited it.

And it came to pass, that while he executed the priest's office,.... To which he was called and ordained, even to offer gifts and sacrifices for men; whilst he was in the way of his duty, when oftentimes God appears to, and in favour of his people; whilst he was performing it,

before God; in the temple, where was the symbol of the divine presence, before the altar of the Lord; and as having the fear of God before his eyes; considering himself as in the sight of God, and doing his work faithfully and sincerely:

in the order of his course; taking his turn in the order of the course of Abia, to which he belonged; See Gill on Luke 1:5.

And it came to pass, that while he executed the priest's office before God in the order of his course,

1:8 While he executed the priest's office. His course came on duty once in twenty-four weeks, and then he repaired to Jerusalem to remain his week.

1:5-25 The father and mother of John the Baptist were sinners as all are, and were justified and saved in the same way as others; but they were eminent for piety and integrity. They had no children, and it could not be expected that Elisabeth should have any in her old age. While Zacharias was burning incense in the temple, the whole multitude of the people were praying without. All the prayers we offer up to God, are acceptable and successful only by Christ's intercession in the temple of God above. We cannot expect an interest therein if we do not pray, and pray with our spirits, and are not earnest in prayer. Nor can we expect that the best of our prayers should gain acceptance, and bring an answer of peace, but through the mediation of Christ, who ever lives, making intercession. The prayers Zacharias often made, received an answer of peace. Prayers of faith are filed in heaven, and are not forgotten. Prayers made when we were young and entering into the world, may be answered when we are old and going out of the world. Mercies are doubly sweet that are given in answer to prayer. Zacharias shall have a son in his old age, who shall be instrumental in the conversion of many souls to God, and preparing them to receive the gospel of Christ. He shall go before Him with courage, zeal, holiness, and a mind dead to earthly interests and pleasures. The disobedient and rebellious would be brought back to the wisdom of their righteous forefathers, or rather, brought to attend to the wisdom of that Just One who was coming among them. Zacharias heard all that the angel said; but his unbelief spake. In striking him dumb, God dealt justly with him, because he had objected against God's word. We may admire the patience of God towards us. God dealt kindly with him, for thus he prevented his speaking any more distrustful, unbelieving words. Thus also God confirmed his faith. If by the rebukes we are under for our sin, we are brought to give the more credit to the word of God, we have no reason to complain. Even real believers are apt to dishonour God by unbelief; and their mouths are stopped in silence and confusion, when otherwise they would have been praising God with joy and gratitude. In God's gracious dealings with us we ought to observe his gracious regards to us. He has looked on us with compassion and favour, and therefore has thus dealt with us.
