Luke 24:53

The Spirit had not yet come, and yet their conversation is spiritual. Before they were shut up; now they stand in the midst of the chief priests; distracted by no worldly object, but despising all things, they praise God continually; as it follows, Praising and blessing God. Whom imitating, may we ever dwell in a holy life, praising and blessing God; to Whom be glory and blessing and power, for ever and ever. Amen.

And they were watching, praying, and fasting, because indeed they were not living in their own homes, but were abiding in the temple, expecting the grace from on high; among other things also learning from the very place piety and honesty. Hence it is said, And were continually in the temple.

When the Lord ascended into heaven, the disciples adoring Him where His feet lately stood, immediately return to Jerusalem, where they were commanded to wait for the promise of the Father; for it follows, And they worshipped him, and returned, &c. Great indeed was their joy, for they rejoice that their God and Lord after the triumph of His resurrection had also passed into the heavens.

And observe that among the four beasts in heaven, (Ezek. 1:10. Rev. 4:7) Luke is said to be represented by the calf, for by the sacrifice of a calf, they were ordered to be initiated who were chosen to the priesthood; (Exod. 29:1.) and Luke has undertaken to explain more fully than the rest the priesthood of Christ; and his Gospel, which he commenced with the ministry of the temple in the priesthood of Zacharias, he has finished with the devotion in the temple. And he has placed the Apostles there, about to be the ministers of a new priesthood, not in the blood of sacrifices, but in the praises of God and in blessing, that in the place of prayer and amidst the praises of their devotion, they might wait with prepared hearts for the promise of the Spirit.
