Leviticus 18:1

וְכָל־נֶפֶשׁ אֲשֶׁר תֹּאכַל נְבֵלָה וּטְרֵפָה בָּאֶזְרָח וּבַגֵּר וְכִבֶּס בְּגָדָיו וְרָחַץ בַּמַּיִם וְטָמֵא עַד־הָעֶרֶב וְטָהֵֽר

And every soul that eateth that which dieth of itself, or that which is torn of beasts, whether he be home-born or a stranger, he shall wash his clothes, and bathe himself in water, and be unclean until the even; then shall he be clean.

וְאִם לֹא יְכַבֵּס וּבְשָׂרוֹ לֹא יִרְחָץ וְנָשָׂא עֲוֺנֽוֹ

But if he wash them not, nor bathe his flesh, then he shall bear his iniquity.

דַּבֵּר אֶל־בְּנֵי יִשְׂרָאֵל וְאָמַרְתָּ אֲלֵהֶם אֲנִי יְהוָה אֱלֹהֵיכֶֽם

Speak unto the children of Israel, and say unto them: I am the LORD your God.

כְּמַעֲשֵׂה אֶֽרֶץ־מִצְרַיִם אֲשֶׁר יְשַׁבְתֶּם־בָּהּ לֹא תַעֲשׂוּ וּכְמַעֲשֵׂה אֶֽרֶץ־כְּנַעַן אֲשֶׁר אֲנִי מֵבִיא אֶתְכֶם שָׁמָּה לֹא תַעֲשׂוּ וּבְחֻקֹּתֵיהֶם לֹא תֵלֵֽכוּ

After the doings of the land of Egypt, wherein ye dwelt, shall ye not do; and after the doings of the land of Canaan, whither I bring you, shall ye not do; neither shall ye walk in their statutes.
