When the smoke of the sacrifices nourishes the negative side on their different levels, they don’t go out to the world to inflict judgments in the Holy Land.
Evening, ‘ערב’, pronounced ‘Erev’ as in ‘ערב רב’, ‘Erev Rav’, which is the mix multitude.
“וְגַם עֵרֶב רַב עָלָה אִתָּם וְצֹאן וּבָקָר מִקְנֶה כָּבֵד מְאֹד”
“A mixed multitude also went up with them, along with flocks and herds, a very large number of livestock.”
The Zohar explains that this verse reveals the aspect of negative entities that get mixed with the night that is the time controlled by the other side. The evening prayer is not mandatory because only Jacob, the central column, can make the proper correction to Malchut.
Even though the evening prayer is not mandatory, it was made by the sages to provide us with protection from the negative forces of the night. During the night, the judgments that can be inflicted b the other side is doubled that what the can do during the night because they have the support of the absence of light.
We start the evening prayer with (Psalms 78:38)
“וְהוּא רַחוּם יְכַפֵּר עָוֹן וְלֹא יַשְׁחִית וְהִרְבָּה לְהָשִׁיב אַפּוֹ וְלֹא יָעִיר כָּל חֲמָתוֹ”
“But He, being compassionate, forgive their iniquity and did not destroy them; And often He restrained His anger And did not arouse all His wrath.”
This verse protects us from three angels of the other side that control hell. Their names are destruction, anger and wrath.
