Fleischig and Milchig??
(ז) וְאֶל־הַבָּקָ֖ר רָ֣ץ אַבְרָהָ֑ם וַיִּקַּ֨ח בֶּן־בָּקָ֜ר רַ֤ךְ וָטוֹב֙ וַיִּתֵּ֣ן אֶל־הַנַּ֔עַר וַיְמַהֵ֖ר לַעֲשׂ֥וֹת אֹתֽוֹ׃ (ח) וַיִּקַּ֨ח חֶמְאָ֜ה וְחָלָ֗ב וּבֶן־הַבָּקָר֙ אֲשֶׁ֣ר עָשָׂ֔ה וַיִּתֵּ֖ן לִפְנֵיהֶ֑ם וְהֽוּא־עֹמֵ֧ד עֲלֵיהֶ֛ם תַּ֥חַת הָעֵ֖ץ וַיֹּאכֵֽלוּ׃
(7) And Abraham ran unto the herd, and fetched a calf tender and good, and gave it unto the servant; and he hastened to dress it. (8) And he took curd, and milk, and the calf which he had dressed, and set it before them; and he stood by them under the tree, and they did eat.

(ח) וכן ויתן, ונתן לפניהם חמאה וחלב ובן הבקר, שיאכלו מאיזה שירצו או מהכל.

(8) ויתן, he placed before them butter and milk as well as the young calf. He offered them the choice to eat either dairy or meaty.

(יט) רֵאשִׁ֗ית בִּכּוּרֵי֙ אַדְמָ֣תְךָ֔ תָּבִ֕יא בֵּ֖ית יְהוָ֣ה אֱלֹהֶ֑יךָ לֹֽא־תְבַשֵּׁ֥ל גְּדִ֖י בַּחֲלֵ֥ב אִמּֽוֹ׃ (ס)

(19) The choicest first-fruits of thy land thou shalt bring into the house of the LORD thy God. Thou shalt not seethe a kid in its mother’s milk.
