Everyone who keeps the Sabbath, happy is he in this world and happy will he be in the world to come, as it is said, "Happy is the man that doeth this, and the son of man that holdeth fast by it: who keepeth the Sabbath from profaning it" (Isa. 56:2). Do not read "(He who keepeth the Sabbath) from profaning it," but read "He who keepeth the Sabbath is pardoned" concerning all his transgression.
THE CREATION ON THE EVE OF THE SABBATH TEN things were created (on the eve of the Sabbath) in the twilight (namely): the mouth of the earth; the mouth of the well; the mouth of the ass; the rainbow; the Manna; the Shamir; the shape of the alphabet; the writing and the tables (of the law); and the ram of Abraham. (Some sages say: the destroying spirits also, and the sepulchre of Moses, and the ram of Isaac; and other sages say: the tongs also.)
