I said to the fools, "Do not be foolish." Rabbi Berachiah said in the name of Rabbi Levi, "It is written (Psalms 104:31), 'May the glory of the Lord endure forever.' When the Holy One, blessed be He, created the world, what is written (Genesis 1:31)? 'And God saw all that He had made, and behold it was very good.'
The word 'saw' should be understood to mean 'rejoiced,' as it says (Exodus 4:14), 'And he will see you and rejoice in his heart.' Once you sinned, I lifted My Shechinah (Divine Presence) on high, and I am the God of the world, and I did not rejoice in My world, while the wicked are rejoicing. It is written (Psalms 104:31), 'Let the Lord rejoice in His works,' but it is not written here that He rejoices now, only in the future, and the wicked are rejoicing.
Therefore, I said to the fools, 'Do not be foolish.' And the sages say that this refers to Elisheva bat Amminadav, who had four joys in her possession: Moses, her brother-in-law; Aaron, her husband; her brother Nahshon, the prince; and her two sons, who were deputy high priests. They entered to offer incense and were consumed by fire, as it says (Leviticus 10:1-2), 'And fire came forth from before the Lord and consumed them, and they died.'
The righteous do not rejoice in this world, while the wicked do rejoice. Therefore, I said to the fools, 'Do not be foolish.' "
