Halakhah su Proverbi 25:29

Indeed, such considerations often led to formal rabbinic legislation designed to establish a fence around that which is biblically prohibited. The Mishnah, Shabbat 153a, indicates the manner in which a wayfarer who fails to reach his destination before the advent of Shabbat may safeguard his wallet and other valuables. Transporting an object a distance less than four cubits wholly within the public domain involves no infraction. Therefore, the Gemara, Shabbat 153b, in its discussion of the Mishnah, questions why the Mishnah does not advise a person to employ the simple expedient of transporting the valuables for a distance of less than four cubits, stopping or placing the object on the ground⁴Some authorities advise the person to sit or to place the object on the ground; others deem stopping to be sufficient. See Mishnah Berurah 266:18. and then repeating the process as many times as necessary until reaching a secure place. Citing the verse "Honor of God [requires] concealing a matter" (Proverbs 25:2), the Gemara declares that this information was purposely suppressed lest a person in such a situation transport the object over a distance greater than that which is, in fact, permitted. The Gemara further indicates that, in this instance, because of a fear of actual desecration of the Sabbath, the Sages promulgated a formal ordinance prohibiting the carrying of valuables in a public thoroughfare for a distance of less than four cubits when another expedient is available. In a similar vein, the Gemara, Shabbat 115a, reports that, upon becoming aware of the fact that his family was engaging in a certain practice in an improper manner, Rabbah informed members of his household that R. Yoḥanan had forbidden the practice entirely.⁵See Oraḥ Meisharim, no. 9.
