Acts 1:12

"Then Returned They," it is said: namely, when they had heard. For they could not have borne it, if the angel had not referred them to another Coming. It seems to me, that it was also on a sabbath-day that these things took place; for he would not thus have specified the distance, saying, "from the mount called Olivet, which is from Jerusalem a sabbath day's journey," unless they were then going on the sabbath-day a certain definite distance.

So that there was no long way to go, to be a cause of alarm to them while yet trembling and fearful.

One mile, which was the distance of the Sabbath's journey, as Origen says in the fifth Homily, was two thousand cubits. And moreover the holy tent and the ark occupied this same space before the encampment, and from that distance they encamped. The distance permitted those who worshipped the holy tent to walk on the Sabbath.

Then they returned to Jerusalem from the mount called Olivet. Our Lord and Savior, having conquered the prince of darkness, leads the faithful to a place of peace and light. Rightly he ascended the mount of blessing, promising the holy Spirit, whose anointing teaches us about everything.

He is near Jerusalem, having the distance of a Sabbath journey. According to history, it indicates that the Mount of Olives is separated by about a mile from the city of Jerusalem. For on the Sabbath, according to the law, it was not permitted to go more than a thousand paces. But according to allegory, whoever will be worthy to contemplate within the glory of the Lord ascending to the Father and to be enriched with the promise of the Holy Spirit, this one enters the city of eternal peace by the journey of the Sabbath. And for him, according to Isaiah, there will be a Sabbath from the Sabbath, because whoever here has ceased from perverse work will there rest in celestial recompense. But on the other hand, whoever in this age, as if through the time of six days, has neglected to work for salvation, during that time of perpetual rest, will be excluded from the boundaries of blessed Jerusalem, despising that Gospel: "Pray that your flight may not be in winter or on the Sabbath."

When did "then they returned"? When they heard what was said by the Angels, because they would never have torn themselves away from the place if the Angels had not informed them about the second coming. And it seems to me that this happened on a Sabbath, because Luke would not have indicated the distance in this way: "from the mount called Olivet, which is near Jerusalem, a Sabbath day's journey away." The length of the journey that Jews were permitted to travel on the Sabbath day was fixed. Josephus in his twentieth book of Antiquities relates that the Mount of Olives was eight stadia from Jerusalem. And Origen in his fifth book says: "The Sabbath journey was three cubits." Indeed, the holy tabernacle with the ark preceded the camp by such a distance and was placed at such a distance from it as worshippers were permitted to travel on the Sabbath. This distance is one mile.

That is nearly two miles.
