The Seven Noahide Laws

עַל שִׁשָּׁה דְּבָרִים נִצְטַוָּה אָדָם הָרִאשׁוֹן. עַל עֲבוֹדָה זָרָה. וְעַל בִּרְכַּת הַשֵּׁם. וְעַל שְׁפִיכוּת דָּמִים. וְעַל גִּלּוּי עֲרָיוֹת. וְעַל הַגֵּזֶל. וְעַל הַדִּינִים. אַף עַל פִּי שֶׁכֻּלָּן הֵן קַבָּלָה בְּיָדֵינוּ מִמּשֶׁה רַבֵּנוּ. וְהַדַּעַת נוֹטָה לָהֶן. מִכְּלַל דִּבְרֵי תּוֹרָה יֵרָאֶה שֶׁעַל אֵלּוּ נִצְטַוָּה. הוֹסִיף לְנֹחַ אֵבֶר מִן הַחַי שֶׁנֶּאֱמַר (בראשית ט, ד) "אַךְ בָּשָׂר בְּנַפְשׁוֹ דָמוֹ לֹא תֹאכֵלוּ". נִמְצְאוּ שֶׁבַע מִצְוֹת. וְכֵן הָיָה הַדָּבָר בְּכָל הָעוֹלָם עַד אַבְרָהָם. בָּא אַבְרָהָם וְנִצְטַוָּה יֶתֶר עַל אֵלּוּ בְּמִילָה. וְהוּא הִתְפַּלֵּל שַׁחֲרִית. וְיִּצְחָק הִפְרִישׁ מַעֲשֵׂר וְהוֹסִיף תְּפִלָּה אַחֶרֶת לִפְנוֹת הַיּוֹם. וְיַעֲקֹב הוֹסִיף גִּיד הַנָּשֶׁה וְהִתְפַּלֵּל עַרְבִית. וּבְמִצְרַיִם נִצְטַוָּה עַמְרָם בְּמִצְוֹת יְתֵרוֹת. עַד שֶׁבָּא משֶׁה רַבֵּנוּ וְנִשְׁלְמָה תּוֹרָה עַל יָדוֹ:

Adam, the first man, was commanded with six commandments: 1) idolatry, 2) “blessing” (euphemistically) the Name (of G-d), 3) murder, 4) illicit sexual relations, 5) thievery and, 6) establishing a system of justice. Even though all of these have been received as a Tradition from Moses our Teacher and we can understand the rationale for them, nevertheless, from (verses in) the Torah (we learn that) it was these that they were commanded. A seventh commandment forbidding the eating of a limb torn from a live animal was added for Noah, as it says, “Even flesh, life is in the blood, do not eat of it” (Genesis 9:4). These commandments were universally applicable - until Abraham. With Abraham, circumcision was also commanded and he prayed Shacharis (the Morning Prayer). Isaac separated out a tithe and added another prayer in the afternoon and, with Jacob, the prohibition against eating the sciatic nerve was added, as was the Maariv (Evening) Prayer. In Egypt, Amram was commanded with other precepts and, with Moses our Teacher, the Torah was completed.
