And the whole multitude of the people were praying without at the time of incense.

People's New Testament

1:10 Praying without. The incense itself was a symbol of prayer (Ps 141:2 Re 5:8), and when offered by the priest a bell was rung as a signal to the people in the courts without, who all engaged in prayer in deep silence.

Wesley's Notes

1:10 The people were praying without, at the time of the incense - So the pious Jews constantly did. And this was the foundation of that elegant figure, by which prayer is in Scripture so often compared to incense. Perhaps one reason of ordaining incense might be, to intimate the acceptableness of the prayer that accompanied it; as well as to remind the worshippers of that sacrifice of a sweet - smelling savour, which was once to be offered to God for them, and of that incense, which is continually offered with the prayers of the saints, upon the golden altar that is before the throne, Rev 8:3,4.

Jamieson-Fausset-Brown Bible Commentary

10. praying without-outside the court in front of the temple, where stood the altar of burnt offering; the men and women in separate courts, but the altar visible to all.

the time of incense-which was offered along with the morning and evening sacrifice of every day; a beautiful symbol of the acceptableness of the sacrifice offered on the altar of burnt offering, with coals from whose altar the incense was burnt (Le 16:12, 13). This again was a symbol of the "living sacrifice" of themselves and their services offered daily to God by the worshippers. Hence the language of Ps 141:2; Re 8:3. But that the acceptance of this daily offering depended on the expiatory virtue presupposed in the burnt offering, and pointing to the one "sacrifice of a sweet-smelling savor" (Eph 5:2), is evident from Isa 6:6, 7.

Matthew Henry's Concise Commentary

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.
