וְזָכַרְתָּ֞֗ כִּ֣י־עֶ֤֥בֶד הָיִ֣֙יתָ֙ ׀ בְּאֶ֣רֶץ מִצְרַ֔֗יִם וַיֹּצִ֨אֲךָ֜֩ יְהוָ֤֨ה אֱלֹהֶ֤֙יךָ֙ מִשָּׁ֔ם֙ בְּיָ֤֥ד חֲזָקָ֖ה֙ וּבִזְרֹ֣עַ נְטוּיָ֑֔ה עַל־כֵּ֗ן צִוְּךָ֙ יְהוָ֣ה אֱלֹהֶ֔יךָ לַעֲשׂ֖וֹת אֶת־י֥וֹם הַשַׁבָּֽת׃ (ס)
Targum Jonathan on Deuteronomy
And remember that you were servants in the land of Mizraim, and that the Lord your God delivered and led you out with a strong hand and uplifted arm; therefore the Lord thy God hath commanded thee to keep the Sabbath day.
