This was the first Sabbath, and this its celebration in heaven by God and the angels. The angels were informed at the same time that in days to come Israel would hallow the day in similar manner. God told them: "I will set aside for Myself a people from among all the peoples. This people will observe the Sabbath, and I will sanctify it to be My people, and I will be God unto it. From all that I have seen, I have chosen the seed of Israel wholly, and I have inscribed him as My first-born son, and I sanctified him unto Myself unto all eternity, him and the Sabbath, that he keep the Sabbath and hallow it from all work."
