Exodus – The Fourth Commandment (Zachor)
Exodus 20:8-11
The Decalogue commands Israel to 'remember' the Sabbath day and keep it holy, grounding the commandment in the six days of creation and God's rest on the seventh.
זָכ֛וֹר֩ אֶת־י֥֨וֹם הַשַּׁבָּ֖֜ת לְקַדְּשֽׁ֗וֹ׃ וְי֨וֹם֙ הַשְּׁבִיעִ֔֜י שַׁבָּ֖֣ת ׀ לַיהֹוָ֣ה אֱלֹהֶ֑֗יךָ לֹֽ֣א־תַעֲשֶׂ֣֨ה כׇל־מְלָאכָ֜֡ה אַתָּ֣ה ׀ וּבִנְךָ֣͏ֽ־וּ֠בִתֶּ֗ךָ עַבְדְּךָ֤֨ וַאֲמָֽתְךָ֜֙ וּבְהֶמְתֶּ֔֗ךָ וְגֵרְךָ֖֙ אֲשֶׁ֥֣ר בִּשְׁעָרֶֽ֔יךָ׃ כִּ֣י שֵֽׁשֶׁת־יָמִים֩ עָשָׂ֨ה יְהֹוָ֜ה אֶת־הַשָּׁמַ֣יִם וְאֶת־הָאָ֗רֶץ אֶת־הַיָּם֙ וְאֶת־כׇּל־אֲשֶׁר־בָּ֔ם וַיָּ֖נַח בַּיּ֣וֹם הַשְּׁבִיעִ֑י עַל־כֵּ֗ן בֵּרַ֧ךְ יְהֹוָ֛ה אֶת־י֥וֹם הַשַּׁבָּ֖ת וַֽיְקַדְּשֵֽׁהוּ׃ {ס}
Remember the sabbath day and keep it holy. but the seventh day is a sabbath of the ETERNAL your God: you shall not do any work—you, your son or daughter, your male or female slave, or your cattle, or the stranger who is within your settlements. For in six days GOD made heaven and earth and sea—and all that is in them—and then rested on the seventh day; therefore GOD blessed the sabbath day and hallowed it.
Why it matters — One of the two primary biblical Shabbat commandments, providing the positive 'remember' dimension of Shabbat observance.
