Rabbi Ṭarphon said: The Holy One, blessed be He, rose and came from Mount Sinai and was revealed unto the sons of Esau, as it is said, "And he said, The Lord came from Sinai, and rose from Seir unto them" (Deut. 33:2). And "Seir" means only the sons of Esau, as it is said, "And Esau dwelt in Mount Seir" (Gen. 36:8). The Holy One, blessed be He, said to them: Will ye accept for yourselves the Torah?
They said to Him: What is written therein? He answered them: It is written therein, "Thou shalt do no murder" (Ex. 20:13). They replied to Him: We are unable to abandon the blessing with which Isaac blessed Esau, for he said to him, "By thy sword shalt thou live" (Gen. 27:40). Thence He turned and was revealed unto the children of Ishmael, as it is said, "He shined forth from Mount Paran" (Deut. 33:2).
"Paran" means only the sons of Ishmael, as it is said, "And he dwelt in the wilderness of Paran" (Gen. 21:21). The Holy One, blessed be He, said to them: Will ye accept for yourselves the Torah? They said to Him: What is written therein? He answered them: "Thou shalt not steal" (Ex. 20:15) is written therein.
They said to Him: We are not able to abandon the usage which our fathers observed, for they brought Joseph down into Egypt, as it is said, "For indeed I was stolen away out of the land of the Hebrews" (Gen. 40:15). Thence He sent || messengers to all the nations of the world. He said unto them: Will ye receive for yourselves the Torah? They said to Him: What is written therein?
He said to them: "Thou shalt have no other gods before me" (Ex. 20:3). They said to Him: We have no delight in the Torah, therefore let Him give His Torah to His people, as it is said, "The Lord will give strength unto his people; the Lord will bless his people with peace" (Ps. 29:11). Thence He returned and was revealed unto the children of Israel, as it is said, "And he came from the ten thousands of holy ones" (Deut. 33:2).
The expression "ten thousands" means the children of Israel, as it is said, "And when it rested, he said, Return, O Lord, unto the ten thousands of the thousands of Israel" (Num. 10:36). With Him were thousands twice-told of chariots, even twenty thousand of holy angels, and His right hand was holding the Torah, as it is said, "At his right hand was a fiery law unto them" (Deut. 33:2).
