וַיְמַן֩ לָהֶ֨ם הַמֶּ֜לֶךְ דְּבַר־י֣וֹם בְּיוֹמ֗וֹ מִפַּת־בַּ֤ג הַמֶּ֙לֶךְ֙ וּמִיֵּ֣ין מִשְׁתָּ֔יו וּֽלְגַדְּלָ֖ם שָׁנִ֣ים שָׁל֑וֹשׁ וּמִ֨קְצָתָ֔ם יַֽעַמְד֖וּ לִפְנֵ֥י הַמֶּֽלֶךְ׃
И король назначил для них ежедневную порцию короля'пищу и вино, которое он пил, и чтобы они питались три года; чтобы в конце они могли предстать перед царем.
Ibn Ezra
[Daniel 1:5] Vayman (וַיְמַן - And the king allotted): This is a transitive verb (po'al yotze - פֹּעַל יוֹצֵא). And the meaning is: to give them portions/allotments (manot - מָנוֹת). And the meaning of pat-bag (פַּת־בַּג) is provisions/food (ma'achal - מַאֲכָל). And it is written in Scripture [using a related root word]: “And I will give you le-vag (כתיב: לְבַג - written form) / le-vaz (קרי: לְבַז - read form, for plunder)” [Ezekiel 25:7 - referring to the K'tiv/K'ri]. And the meaning [of bag and baz] is close. Perhaps the specific meaning of bag [here in Daniel] is cooked meat.
Rashi
of... food Heb. מִפַּת־בַּג. That is the name of the king’s fare in the language of the Chaldeans. Some interpret פַּת־בַּג, [as] bread, but it does not appear correct, for it is written (below verse 16): “The steward would take away פַּת־בָּגָם... and give them pulse.” Now pulse is not a substitute for bread, but a substitute for cooked food.
