Leviticus 18:3-4
ב דַּבֵּר אֶל-בְּנֵי יִשְׂרָאֵל, וְאָמַרְתָּ אֲלֵהֶם: אֲנִי, יְהוָה אֱלֹהֵיכֶם. ג כְּמַעֲשֵׂה אֶרֶץ-מִצְרַיִם אֲשֶׁר יְשַׁבְתֶּם-בָּהּ, לֹא תַעֲשׂוּ; וּכְמַעֲשֵׂה אֶרֶץ-כְּנַעַן אֲשֶׁר אֲנִי מֵבִיא אֶתְכֶם שָׁמָּה, לֹא תַעֲשׂוּ, וּבְחֻקֹּתֵיהֶם, לֹא תֵלֵכוּ.
You shall not copy the practices of the land of Egypt, where you dwelt, or of the land of Canaan, to which I am bringing you. You shall not follow their laws. My regulations you are to do, my laws you are to keep by following them; I am YHVH your God. [Translation by Rabbi Steven Greenberg]
