וְעָשִׂ֨יתָ לּ֥וֹ מִסְגֶּ֛רֶת טֹ֖פַח סָבִ֑יב וְעָשִׂ֧יתָ זֵר־זָהָ֛ב לְמִסְגַּרְתּ֖וֹ סָבִֽיב׃
그 사면에 손바닥 넓이만한 턱을 만들고 그 턱 주위에 금으로 테를 만들고
Rashi on Exodus
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).
Rashbam on Exodus
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.
Chizkuni
ועשית לו מסגרת טפח, “you are to construct for it a rim one handbreadth wide all around.”
