Zohar Chayei Sarah
Balaam was getting into the high impure state by having sex with animals. After that, he could perform his witchcraft
A man should not come close to a woman during the time of her menstrual cycle. Because this cycle caused by the first sin with the Snake, the impure spirit gets attached to the woman. During her period, a woman can be more successful in making witchcraft than at other times. Whatever she touches, would have impurity.
The Israelites are blessed for having the Torah and follow the command that saves them from the negative and impure side.
“וְאֶל אִשָּׁה בְּנִדַּת טֻמְאָתָהּ לֹא תִקְרַב לְגַלּוֹת עֶרְוָתָהּ.”
“’Also you shall not approach a woman to uncover her nakedness during her menstrual impurity.”
There are people that can watch and listen to birds to know about the future. It’s called ‘נחש’ ‘snake’ and witchcraft because all impurities come from the side of the Snake. The impure spirit would stay in the world until God removes it.
“בִּלַּע הַמָּוֶת לָנֶצַח וּמָחָה אֲדֹנָי יְהוִה דִּמְעָה מֵעַל כָּל פָּנִים וְחֶרְפַּת עַמּוֹ יָסִיר מֵעַל כָּל הָאָרֶץ כִּי יְהוָה דִּבֵּר.”
“He will swallow up death for all time, And YHVH GOD will wipe tears away from all faces, And He will remove the reproach of His people from all the earth; For YHVH has spoken.”
“וְהָיָה בַיּוֹם הַהוּא נְאֻם יְהוָה צְבָאוֹת אַכְרִית אֶת שְׁמוֹת הָעֲצַבִּים מִן הָאָרֶץ וְלֹא יִזָּכְרוּ עוֹד וְגַם אֶת הַנְּבִיאִים וְאֶת רוּחַ הַטֻּמְאָה אַעֲבִיר מִן הָאָרֶץ.”
“It will come about in that day,” declares YHVH of hosts, “that I will cut off the names of the idols from the land, and they will no longer be remembered, and I will also remove the prophets and the unclean spirit from the land.”
