Musar su I Cronache 16:33

The North Wind — This wind blows from midnight until the morning. It was taught: Three hundred thousand storm and tempest winds come with it. It interferes with everything. Yet for the infirm it is good, for these winds are cool and the feverish find relief in this coolness. It was taught: Rabbi Shimon ben Yochai said: At that time the Holy One Blessed is He leaves the many worlds to delight with the righteous in Gan Eden. And a herald’s voice proclaims, “Awake, O North, and come, O South” (Shir HaShirim 4:16) and cause the spices of Gan Eden to waft. For it is taught: At the time that the north wind blows at midnight and the Holy One Blessed is He enters Gan Eden, all the spices and all the trees of Gan Eden give forth their fragrance and sing before Him, as it is written, “Then the trees of the forest will exult before Hashem” (I Divrei HaYamim 16:33). And all the angels of Heaven and all the firmaments and the Holy Creatures and the Ofanim shudder and open their mouths in exultation and praise to the One who spoke and the world came into being. Until the Holy One Blessed is He enters Gan Eden together with the righteous, which takes place at midnight.
