Exodus 25:12

ויצקת — a term used of casting metal, as the Targum has it. פעמתיו — Understand this as the Targum renders it: ON ITS CORNERS. It was on the upper corners near to the cover that the rings were placed — two on one side of the ark and two on the other along the breadth of the ark, and the staves were put into them (the rings). The length of the ark thus formed a space of two cubits and a half between one stave and the other so that two men who were carrying the ark could walk with ease between on the same side. Thus is it explained in Treatise Menachot in the section beginning with the words, "Shtei HaLehem" (Menachot 98b). שתי הלחם ושתי טבעות על צלעו האחת AND TWO RINGS IN THE ONE SIDE OF IT — These are the very four rings spoken of in the beginning of the verse but here Scripture explains to you where they were fixed. This ו of the word ושתי (the first time the word occurs here) is really redundant and the interpretation is as though it read, שתי טבעת (see Note on Exodus 24:12). Since however the ו is there you may make it fit in thus: and two of these rings shall be on the one side of it and two on the other side thereof. צלעו means THE SIDE OF IT.

And thou shalt cast four rings of gold for it, and put them in its four corners, and two rings shall be on the one side of it, and two rings on the other side of it.
