By bestowing Sabbath joy upon all beings, not excepting Adam, thus did the Lord dedicate His creation. Seeing the majesty of the Sabbath, its honor and greatness, and the joy it conferred upon all, being the fount of all joy, Adam intoned a song of praise for the Sabbath day. Then God said to him, "Thou singest a song of praise to the Sabbath day, and singest none to Me, the God of the Sabbath?" Thereupon the Sabbath rose from his seat, and prostrated himself before God, saying, "It is a good thing to give thanks unto the Lord," and the whole of creation added, "And to sing praises unto Thy Name, O Most High!"[101] 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."[102] For Adam the Sabbath had a peculiar significance. When he was made to depart out of Paradise in the twilight of the Sabbath eve, the angels called after him, "Adam did not abide in his glory overnight!" Then the Sabbath appeared before God as Adam's defender, and he spoke: "O Lord of the world! During the six working days no creature was slain. If Thou wilt begin now by slaying Adam, what will become of the sanctity and the blessing of the Sabbath?" In this way Adam was rescued from the fires of hell, the meet punishment for his sins, and in gratitude he composed a psalm in honor of the Sabbath, which David later embodied in his Psalter.[103] Still another opportunity was given to Adam to learn and appreciate the value of the Sabbath. The celestial light, whereby Adam could survey the world from end to end, should properly have been made to disappear immediately after his sin. But out of consideration for the Sabbath, God had let this light continue to shine, and the angels, at sundown on the sixth day, intoned a song of praise and thanksgiving to God, for the radiant light shining through the night. Only with the going out of the Sabbath day the celestial light ceased, to the consternation of Adam, who feared that the serpent would attack him in the dark. But God illumined his understanding, and he learned to rub two stones against each other and produce light for his needs.[104]
