Komentarz do Wyjścia 25:25

מסגרת — Understand this as the Targum renders it: גדנפא, A RIM. The Sages in Israel are of different opinion as to what this מסגרת signifies. Some say it was on top all the way round the table like the vertical ledge that is on the edges of the table of noble men, whilst others say it was fixed beneath the table from leg to leg on the four sides of the table and that the table-top rested upon that ledge (cf. Menachot 96b and Sukkah 5a).

מסגרת, a kind of rim or edge which it is customary to attach to top of tables, to guard against spillage. Others say that it was attached to the underside of the tables reinforcing the legs at each corner.

ועשית לו מסגרת טפח, “you are to construct for it a rim one handbreadth wide all around.”
