The mountain on which God made his revelation bears six names: It is called the Desert Sin, because God there announced His commandments; it is called the Desert Kadesh, because Israel was sanctified there; the Desert Kadmut because the pre-existing Torah was there revealed; the Desert Paran because Israel there was greatly multiplied; the Desert Sinai because the hatred of God against the heathens began there, for the reason that they would not accept the Torah; and for this same reason is it called Horeh, because the annihilation of the heathens was there decreed by God.  For the wrath of God against the heathens dates from their refusal to accept the Torah offered them.
Before God gave Israel the Torah, He approached every tribe and nation, and offered them the Torah, that hereafter they might have no excuse to say, "Had the Holy one, blessed be He, desired to give us the Torah, we should have accepted it." He went to the children of Esau and said, "Will ye accept the Torah?" They answered Him, saying, "What is written therein?" He answered them, "Thou shalt not kill." Then they all said: "Wilt Thou perchance take from us the blessing with which our father Esau was blessed? For he was blessed with the words, 'By thy sword shalt thou live." We do not want to accept the Torah." Thereupon He went to the children of Lot and said to them, "Will ye accept the Torah?" They said, "What is written therein?" He answered, "Thou shalt not commit unchastity." They said: "From unchastity do we spring; we do no want to accept the Torah." Then He went to the children of Ishmael and said to them, "Do ye want to accept the Torah?" They said to Him, "What is written therein?" He answered, "Thou shalt not steal." They said: "Wilt Thou take from us the blessing with which our father was blessed? God promised him: 'His hand will be against every man.' We do not want to accept the Thy Torah." Thence He went to all the other nations, who likewise rejected the Torah, saying: "We cannot give up the law of our fathers, we do not want Thy Torah, give it to Thy people Israel." Upon this He came to Israel and spoke to them, "Will ye accept the Torah?" They said to Him, "What is written therein?" He answered, "Six hundred and thirteen commandments." They said: "All that the Lord has spoken will we do and be obedient."  "O Lord of the world!" they continued, "We acted in accordance with Thy commandments before they were revealed to us. Jacob fulfilled the first of the Ten Commandments by bidding his sons put away strange gods that were among them. Abraham obeyed the commandment not to take the name of the Lord in vain, for he said: 'I have lifted up mine hand unto the Lord, the most high God.' Joseph fulfilled the commandment to remember the Sabbath and keep it holy; and when his brothers came to him, he had everything for their welcome prepared on Friday. Isaac observed the law to honor his father and his mother, when he allowed Abraham to bind him on the altar as a sacrifice. Judah observed the commandment not to kill when he said to his brothers, 'What profit is it if we slay our brother and conceal his blood?' Joseph observed the law: 'Thou shalt not commit adultery,' when he repulsed the desire of the wife of Potiphar. The other sons of Jacob observed the commandment: 'Thou shalt not steal,' saying: 'How then should we steal out of thy lord's house silver and gold?' Abraham observed the commandment: 'Thou shalt not bear false witness,' for he was a true witness, and bore witness before all the world that Thou art the Lord of all creation. It was Abraham, also, who observed the last of the Ten Commandments 'Thou shalt not covet,' saying: 'I will not take from a thread even to a shoe-latchet.'"
