신명기 5:12의 Halakhah

In Deuteronomy 5:12 the admonition is couched in different terms. "Shamor et yom ha-Shabbat le-kadesho—Observe the Sabbath day to keep it holy." The rationale incorporated in this formulation is a completely different one: "And you shall remember that you were a servant in the land of Egypt and the Lord your God brought you out of there with a mighty hand and with an outstretched arm; therefore the Lord your God commanded you to keep the Sabbath day." Here the Torah bids us remember that we were once slaves in Egypt and emphasizes that it was to this end that God commanded us to institute the Sabbath.
