וְזָכַרְתָּ֗ כִּ֣י עֶ֤בֶד הָיִ֙יתָ֙ בְּמִצְרַ֔יִם וַֽיִּפְדְּךָ֛ יְהוָ֥ה אֱלֹהֶ֖יךָ מִשָּׁ֑ם עַל־כֵּ֞ן אָנֹכִ֤י מְצַוְּךָ֙ לַעֲשׂ֔וֹת אֶת־הַדָּבָ֖ר הַזֶּֽה׃ (ס)
你要記住，你在埃及曾作過奴僕，永恆者你的上帝把你從那裡贖出來；所以我吩咐你遵行這件事。
Rashi
וזכרת BUT THOU SHALT REMEMBER [THAT THOU WAST A SERVANT IN EGYPT AND THE LORD THY GOD RELEASED THEE THENCE] — I released you only with this condition — that you should observe my statutes even though there be monetary loss in the matter.
Ibn Ezra
remember that you were a slave and consequently you should remember the alien, and not deny him justice. Some of these commandments were already mentioned to the older generation, and are now repeated to the younger generation.
Ramban
AND THOU SHALT REMEMBER THAT THOU WAST A BONDMAN IN EGYPT. “I have redeemed you on the condition that you observe My statutes even though it may involve monetary loss.” This is Rashi’s language. But the correct interpretation is that it refers back to the admonitions concerning the stranger. I have already explained the meaning thereof.365Exodus 22:20 (Vol. II, pp. 392-393). See also above at end of Seder R’eih.
