לַֽמְאַחֲרִ֥ים עַל־הַיָּ֑יִן לַ֝בָּאִ֗ים לַחְקֹ֥ר מִמְסָֽךְ׃
Tym, którzy do późna przesiadują przy winie, którzy przychodzą, by napój wypróbować.
Rashi
mingled wine Heb. מִמְסָךְ, wine mingled with water as was customary. Comp. (Prov. 23:30) “To search for mingled wine (מִמְסָךְ).” Also (ibid. 9:2), “She mingled (מָסְכָה) her wine.” Some interpret לַמְנִי, to the pagan deities that you appointed (מִנִּיתֶם) over yourselves, but וּמָנִיתִי אֶתְכֶם, which is not punctuated וּמִנִּיתִי with a ‘dagesh,’ indicates that it is an expression of counting.
Radak
He continues: חכלילי עינים מיין ולבן שנים מחלב, having already mentioned wine as symbolising fragrance as well as symbolising an impressive appearance, he did so because he views them as the most appropriate description of something that looks pleasant and inspiring. Such a perception of what looks beautiful is also echoed in Lamentations 4,7 ”Her elect were purer than snow and whiter than milk,” and in Song of Songs 5,10 the example for such a lovely appearance is “my beloved is clear-skinned and ruddy.” The appearance of wine is most impressive and it is reddish and sparkling as described in Proverbs 23,31 “do not ogle that red wine as it lends its colour to the cup.” It is described as if giving off sparks. Pure white colour is also extolled in Exodus 24,10 when the elders before the revelation at Mount Sinai feasted their eyes on a Divine appearance described as “like a brick of sapphire, and the essence of the heavens in purity.” The whitest parts of the human body are the teeth They are praised for their whiteness also in Song of Songs 6,6 where their whiteness is compared to that of “a flock of ewes climbing up from the washing pool.” [The author continues in this vein for a few more lines. Ed.] The point he is trying to make is that over and beyond any physical perfection we know of in this world, the perfection of virtues, albeit intangible, is superior to anything perfect but tangible on earth. Hence the superiority of the Messiah with his virtues and supernatural qualities. Yaakov, using his prophetic insights, addresses each of his sons with the degree of prophetic insight he has been granted in describing the future in store for him.
