Shemot 38:26

בקע (from בָּקַע to split) is the name given to a weight of half a shekel. לשש מאות אלף וגו׳ FOR SIX HUNDRED THOUSAND [AND THREE THOUSAND etc.] — Thus were the Israelites in number, and thus did their number amount to after the Tabernacle was set up, as it is stated in the Book of Numbers (ch. II), and at this time, also, when they contributed toward the Tabernacle they were just as many (cf. Rashi on Exodus 30:16). The half-shekels of 600,000 amount to a hundred talents, each talents consisting of three thousand shekels (cf. v. 25). How is this? 600,000 half-shekels are 300,000 whole shekels, making one hundred talents and the remaining 3550 half-shekels make 1775 whole shekels, as stated in the text.

בֶּ֚קַע לַגֻּלְגֹּ֔לֶת מַחֲצִ֥ית הַשֶּׁ֖קֶל בְּשֶׁ֣קֶל הַקֹּ֑דֶשׁ לְכֹ֨ל הָעֹבֵ֜ר עַל־הַפְּקֻדִ֗ים מִבֶּ֨ן עֶשְׂרִ֤ים שָׁנָה֙ וָמַ֔עְלָה לְשֵׁשׁ־מֵא֥וֹת אֶ֙לֶף֙ וּשְׁלֹ֣שֶׁת אֲלָפִ֔ים וַחֲמֵ֥שׁ מֵא֖וֹת וַחֲמִשִּֽׁים׃

a beqa for every man, that is, half a shekel, after the shekel of the sanctuary, for everyone that went to be numbered, from twenty years old and upward, for six hundred and three thousand, five hundred and fifty men.
