“וְלָקַח הַכֹּהֵן מַיִם קְדֹשִׁים בִּכְלִי חָרֶשׂ וּמִן הֶעָפָר אֲשֶׁר יִהְיֶה בְּקַרְקַע הַמִּשְׁכָּן יִקַּח הַכֹּהֵן וְנָתַן אֶל הַמָּיִם”
“and the priest shall take holy water in an earthenware vessel; and he shall take some of the dust that is on the floor of the tabernacle and put it into the water.”
Everything came from dust and goes back to dust, man and even the sun in the sky.
‘from the dust’ is simply Malchut but the verse uses dust that is on the floor of the Tabernacle’. It means that there’s a different type of dust.
To bring Light to the entire world, the Tabernacle is at the end of Malchut. For that reason, at the bottom we find aspects of judgments holding in the Malchut of Malchut. The priest takes from this dust and add to the water to mix mercy and judgment that will reveal the truth if the woman is unfaithful and connected to ‘foreign’ energy that contaminated her vessel.
“וְהֶעֱמִיד הַכֹּהֵן אֶת הָאִשָּׁה לִפְנֵי יְהוָה וּפָרַע אֶת רֹאשׁ הָאִשָּׁה וְנָתַן עַל כַּפֶּיהָ אֵת מִנְחַת הַזִּכָּרוֹן מִנְחַת קְנָאֹת הִוא וּבְיַד הַכֹּהֵן יִהְיוּ מֵי הַמָּרִים הַמְאָרֲרִים”
“The priest shall then have the woman stand before YHVH and let the hair of the woman’s head go loose, and place the grain offering of memorial in her hands, which is the grain offering of jealousy, and in the hand of the priest is to be the water of bitterness that brings a curse.”
Malchut is also called ‘sea’ and ‘the water of bitterness’ is the aspect of water of the sea. They are bitter because they are in a state of Malchut in judgment and ‘that brings a curse’.
