אִם־עֶ֛בֶד יִגַּ֥ח הַשּׁ֖וֹר א֣וֹ אָמָ֑ה כֶּ֣סֶף ׀ שְׁלֹשִׁ֣ים שְׁקָלִ֗ים יִתֵּן֙ לַֽאדֹנָ֔יו וְהַשּׁ֖וֹר יִסָּקֵֽל׃ (ס)
牛若牴死男僕或婢女，牛的主人就要把三十舍客勒銀子給他們的主人，那牛也必須用石頭打死。
Mishneh Torah, Sheqel Dues
The silver denomination spoken about in the Torah regarding rape, seduction, one who puts out a bad name and one who kills a slave – that silver denomination is the shekel that is spoken about in every [other] place in the Torah. And its weight is three hundred and twenty barley seeds. And the Sages already added to it and made its weight [to be] like the weight of the coin called, [the] sela, at the time of the Second Temple. And how much is the weight of the sela? Three hundred eighty four medium barley grains.
