Tafsiran Yehezkiel 45:12: Rashi

And the shekel is twenty gerah Twenty “ma’ah.”

twenty shekels, twenty-five shekels, and fifteen shekels totaling sixty shekels.

shall the maneh be to you Le zent in O. F., the 100 (zuz weight). Menahem, however, connected it to the word מִנְיָן, a number (p. 118). We have here 240 “zuz,” [four zuz to a shekel]. From here we derive that the “maneh” of the Sanctuary was double, and they added a sixth to it in Ezekiel’s time, totaling 240 [zuz] (Men. 77a). When Scripture divided it into three parts and did not write simply, “sixty shekels shall the maneh be for you,” it commanded to make from it a weight one third of it, and a weight equaling a fourth of it, and a weight of the ordinary “maneh” as it was originally. So too did Jonathan paraphrase: a third of the “maneh” shall be twenty “selaim” of silver; a “maneh” of silver twenty-five “selaim”; a fourth of a “maneh”fifteen “selaim”; altogether, sixty “selaim”; and the great “maneh” of the Sanctuary shall be for you.
