Rashi
shall vanish Heb. נִמְלָחוּ, shall rot away. Comp. (Jer. 38:12) “Rags and decayed clothing (בְּלוֹאֵי הַסְּחָבוֹת),” a decayed garment. Another explanation of נִמְלָחוּ is: shall be stirred. This is an expression similar to “the sailors of (מַלָּחֵי) the sea,” who stir the water with the oars that guide the ship. Comp. also (Ex. 30:35) “Stirred (מְמֻלָּח), pure, and holy.”
Ibn Ezra
fragrant incense of the type already specified [Exodus 30:35]
Sforno
ואת קטורת הסמים טהור; with spices from which any foreign elements had been carefully removed, i.e. טהור, “pure, unadulterated.”
