1:12

a sabbath day’s journey: That is, the distance an Israelite was allowed to travel on the Sabbath. The term is here connected with the distance between the Mount of Olives and the city of Jerusalem. The Law restricted travel on the Sabbath but did not specify the distance that could be covered. (Ex 16:29) Over time, rabbinic sources defined the distance a Jew could travel on that day as being about 2,000 cubits (890 m; 2,920 ft). That interpretation was based on Nu 35:5: “You should measure outside the city 2,000 cubits” and on the statement found at Jos 3:3, 4 that instructed the Israelites to keep a distance of about 2,000 cubits from “the ark of the covenant.” Rabbis reasoned that an Israelite was permitted to travel at least that far on the Sabbath to worship at the tabernacle. (Nu 28:9, 10) Possibly because of reckoning from two different starting points, Josephus gives the distance between Jerusalem and the Mount of Olives one time as five furlongs (925 m; 3,034 ft) and another time as six furlongs (1,110 m; 3,640 ft). Either way, the distance is approximately the same as the distance that the rabbis had defined as a sabbath day’s journey, and it harmonizes with Luke’s comment in this verse.
