(12) Observe the sabbath day and keep it holy, as the LORD your God has commanded you. (13) Six days you shall labor and do all your work, (14) but the seventh day is a sabbath of the LORD your God; you shall not do any work—you, your son or your daughter, your male or female slave, your ox or your ass, or any of your cattle, or the stranger in your settlements, so that your male and female slave may rest as you do. (15) Remember that you were a slave in the land of Egypt and the LORD your God freed you from there with a mighty hand and an outstretched arm; therefore the LORD your God has commanded you to observe the sabbath day.

(8) Remember the sabbath day and keep it holy. (9) Six days you shall labor and do all your work, (10) but the seventh day is a sabbath of the LORD 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. (11) For in six days the LORD made heaven and earth and sea, and all that is in them, and He rested on the seventh day; therefore the LORD blessed the sabbath day and hallowed it.
ושתי חצוצרות מן הצדדים: ותרי קלי מי משתמעי והתניא זכור ושמור בדיבור אחד נאמרו מה שאין הפה יכולה לדבר ואין האוזן יכולה לשמוע לכך מאריך בשופר
§ It was taught in the mishna: And there were two trumpets, one on each of the two sides of the person sounding the shofar. The Gemara asks: But is it really possible to properly discern two different sounds, that of the shofar and that of the trumpets, at the same time? Isn’t it taught in a baraita: The two versions of the fourth of the Ten Commandments, “Remember the Shabbat day” (Exodus 20:8) and “Keep the Shabbat day” (Deuteronomy 5:12), were spoken by God simultaneously in a single utterance, something that the human mouth cannot speak and the human ear cannot hear? This indicates that it is impossible to take in two sounds at once, and so, due to the sound of the trumpets, it should be impossible to hear the blast of the shofar. The Gemara answers: For this reason they would sound a long blast with the shofar, to make it possible to hear the sound of the shofar on its own.
(א) שָׁמוֹר וְזָכוֹר בְּדִבּוּר אֶחָד
(ב) הִשְׁמִיעָנוּ אֵל הַמְּיֻחָד
(ג) ה' אֶחָד וּשְׁמוֹ אֶחָד
(ד) לְשֵׁם וּלְתִפְאֶרֶת וְלִתְהִלָּה
(1) "Keep" and "remember" in one saying
(2) We were caused to listen by the Unified God
(3) Adonai is One, and His Name is One
(4) To His name, and to glory and to praise!
Rabbi Jonathan Sacks, Shavuot Mahzor, p. 413:
There are differences between the fourth command as reported in [in Exodus 20:8-11] and in Deuteronomy (5:12-15). [In Exodus] the verb is "remember," [in Deuteronomy] "observe." [In Exodus] Shabbat is a memorial of creation, [in Deuteronomy] of the exodus from Egypt. The sages said that both version were uttered simultaneously (Rosh Hashana 27a; Shevuot 20b). At the simplest level, this means that the Torah says sequentially what is true simultaneously, namely that the God of creation is also the God of redemption. The freedom represented by the day of rest is, on the one hand, the ability to rise beyond nature (creation), and on the other, a respite from human forms of oppression (redemption). Shabbat is a sustained tutorial in the exercise and experience of both forms of liberty.
