English: Hagashah is compared to hakravah: just as bringing-near is by a kohen with a vessel, so presentation is by a kohen with a vessel.
Hekesh of hagashah to hakravah — presentation, like the bringing-near, is performed by a kohen with a vessel.
Presentation is performed by a kohen using a service vessel. The hekesh between hagashah and hakravah teaches that the same requirements of a qualified kohen and a proper vessel apply to the act of presenting the minchah.
