Exodus 16:29

ראו SEE with your very eyes (i. e. the word is used literally and not figuratively in the sense of “consider”) that the Lord in His glory (i. e. the Lord Himself) admonishes you regarding the Sabbath, for, behold, a miracle is performed for you on the eve of every Sabbath in that He gives you then bread for two days. שבו איש תחתיו ABIDE YE EVERY MAN IN HIS PLACE (lit., beneath himself) — From here the Sages derived a support for the permission that a person who has gone beyond the Sabbath limit may move within a space of four cubits (Mekhilta; Eruvin 51a). אל יצא איש ממקמו LET NO MAN GO OUT OF HIS PLACE — These are the 2,000 cubits of the Sabbath limit (Mekhilta); but this is not expressly mentioned here, because the command relating to the Sabbath limits is only an institution of the Sopherim. The text itself was really spoken about those who gathered the Manna (i. e., it does not constitute a prohibition regarding the Sabbath for all men and at all periods but was intended to forbid anyone to go out into the field to gather the Manna; cf. Sotah 30b).

רְא֗וּ כִּֽי־יְהֹוָה֮ נָתַ֣ן לָכֶ֣ם הַשַּׁבָּת֒ עַל־כֵּ֠ן ה֣וּא נֹתֵ֥ן לָכֶ֛ם בַּיּ֥וֹם הַשִּׁשִּׁ֖י לֶ֣חֶם יוֹמָ֑יִם שְׁב֣וּ ׀ אִ֣ישׁ תַּחְתָּ֗יו אַל־יֵ֥צֵא אִ֛ישׁ מִמְּקֹמ֖וֹ בַּיּ֥וֹם הַשְּׁבִיעִֽי׃

See, that the Lord has given you the sabbath, therefore he gives you on the sixth day the bread of two days: remain every man in his place, let no man go out of his place on the seventh day.
