John Gill Bible Commentary

But the earthen vessel wherein it is sodden shall be broken,.... That being porous, the liquor in which the sin offering was boiled might soak into it, and the smell of it be retained, and therefore, as such vessels were not very costly, they were ordered to be broken; but where the broken pieces were carried and laid, the Jewish writers are at a loss about; for, that vessels, which had served for holy uses, should be laid in an open public place and exposed, they thought was indecent; and as there might be in a course of time great quantities broken, it would look very disagreeable and unseemly to have them lie in heaps in the sanctuary; they therefore have framed a miracle, and conceit that they were swallowed up in the ground where they were laid (x): and if it be sodden in a brazen it shall be both scoured and rinsed in water; brass, being more valuable, must not be destroyed; and besides the liquor could not soak into that, and whatever scent it retained was easily and soon removed by scouring and rinsing; the former was with hot water, and the latter with cold, as Ben Gersom affirms. (x) T. Bab. Yoma, fol. 21. 1.
