וְהָיְתָ֥ה לָּהֶ֖ם לְחֻקַּ֣ת עוֹלָ֑ם וּמַזֵּ֤ה מֵֽי־הַנִּדָּה֙ יְכַבֵּ֣ס בְּגָדָ֔יו וְהַנֹּגֵ֙עַ֙ בְּמֵ֣י הַנִּדָּ֔ה יִטְמָ֖א עַד־הָעָֽרֶב׃
Targum Jonathan on Numbers
And it shall be unto you an everlasting statute. The priest, also, who sprinkleth the water of sprinkling shall sprinkle his clothes, and he who toucheth the water of sprinkling shall be unclean until evening.
