Targum Pseudo-Jonathan on Exodus 16:29 transforms a short Hebrew verse into the founding document of the Sabbath's geography: Behold, because I have given you the Sabbath, I gave you on the sixth day bread for two days. Let every man abide in his place, and not wander from one locality to another, beyond four yards; nor let any man go forth to walk beyond two thousand yards on the seventh day.
Four cubits within a locality. Two thousand cubits beyond it. The Targum is quoting the rabbinic laws of techum Shabbat, the Sabbath boundary, which restricts how far one may walk outside one's place on the holy day. The four cubits (roughly six feet) define a person's immediate personal space, the minimum a person can move without "walking." The two thousand cubits (roughly three-quarters of a mile) define how far one may go from the edge of one's city or camp.
These numbers come directly from Mishnah Eruvin (compiled c. 200 CE), the rabbinic tractate devoted to Sabbath domains. The Targumist is reading the Torah's command stay in your place through the fully developed legal lens of the Sages, anchoring the entire system of techum in the wilderness of Sin.
Why does walking matter so much? Because walking is the verb of the weekday. You walk to the field, you walk to the market, you walk to the court. To stop walking is to stop producing. The Sabbath geography is not a cage. It is a container. It says: within this radius, be fully present. Do not scatter yourself across the week's distances.
The Maggid's takeaway is pastoral. You cannot rest if you keep walking. The rabbinic boundaries sound small to modern ears, but their purpose is enormous. They compress your week's radius into a small circle in which everyone you love is reachable on foot. That is Shabbat: the week folded down to the size of a family table.
