Sometimes, accessories ARE included!
Since the Mishkan and its vessels were to be carried through the desert, several items, including the Shulchan and golden Mizbei’ach, had badim, staves, which would be inserted at times of transport. The Aron Kodesh had these “travel handles,” as well, but strangely, its poles remained in place continuously – even while the Ark was parked in the Mishkan. In fact, one of the formal 613 mitzvos is a prohibition against removing the rods from the Aron at any time (Sh’mos 25:15; Sefer HaChinuch, mitzvah 96). One who would dare to separate the badim from the Ark would be in violation of an egregious crime deserving of 39 lashes (Yoma 72a, Makos 22a) – no less than the punishment for eating pork! Why did the Aron Kodesh need to be fully accessorized with its “travel pack” at all times – even when it stood still in the Mishkan?
