English: “And the kohen shall lift” — might [it be] with a vessel? The verse says “and he shall lift from it with his handful” — just as there with his handful, so here with his handful.
Miyut against vessel for lifting the azkarah — the memorial is taken by the hand’s kometz alone.
The memorial portion is taken by the hand’s kometz, not scooped with a utensil. The Torah’s requirement that the kohen lift the azkarah is clarified by the parallel “with his handful,” teaching that a vessel may not be substituted for the hand.
