וְכֹ֛ל אֲשֶׁר־יִגַּע־בּ֥וֹ הַטָּמֵ֖א יִטְמָ֑א וְהַנֶּ֥פֶשׁ הַנֹּגַ֖עַת תִּטְמָ֥א עַד־הָעָֽרֶב׃ (פ)
И что бы ни прикоснулся нечистый человек, он будет нечист; и душа, которая касается его, будет нечистой до смирения.
Panekha Avakesh
There is a connection between the Red Heifer and the sin of the Golden Calf, as explained by Rabbi Moshe HaDarshan, as cited by Rashi. In Numbers 19:22, it states: "And it shall be for them a perpetual statute: that he who sprinkles the water of impurity shall cleanse his clothes, and he who touches the water of impurity shall be unclean until evening." Rashi explains this verse with a parable: The Red Heifer is likened to a maidservant's son who dirtied the king's palace, and they said, "Let his mother come and clean up the filth." Similarly, the Red Heifer comes and atones for the sin of the Golden Calf.
