If it were to be rendered, “and the wine foams,” it would then have been היּין; מסך, which is undoubtedly accusative, also shows that yayin is also not considered as anything else: and it (the cup) foams (חמר like Arab. ‘chtmr, to ferment, effervesce) with wine, is full of mixture. According to the ancient usage of the language, which is also followed by the Arabic, this is wine mixed with water in distinction from merum, Arabic chamr memzûg'e. Wine was mixed with water not merely to dilute it, but also to make it more pleasant; hence מסך signifies directly as much as to pour out (vid., Hitzig on Isa 5:22). It is therefore unnecessary to understand spiced wine (Talmudic קונדיטון, conditum), since the collateral idea of weakening is also not necessarily associated with the admixture of water. מזּה refers to כּוס, which is used as masculine, as in Jer 25:15; the word is feminine elsewhere, and changes its gender even here in שׁמריה (cf. Eze 23:34). In the fut. consec. ויּגּר the historical signification of the consecutive is softened down, as is frequently the case. אך affirms the whole assertion that follows. The dregs of the cup - a dira necessitas - all the wicked of the earth shall be compelled to sip (Isa 51:17), to drink out: they shall not be allowed to drink and make a pause, but, compelled by Jahve, who has appeared as Judge, they shall be obliged to drink it out with involuntary eagerness even to the very last (Eze 23:34). We have here the primary passage of a figure, which has been already hinted at in Psa 60:5, and is filled in on a more and more magnificent and terrible scale in the prophets. Whilst Obadiah (Oba 1:16, cf. Job 21:20) contents himself with a mere outline sketch, it is found again, in manifold applications, in Isaiah, Habakkuk, and Ezekiel, and most frequently in Jeremiah (Jer 25:27., Jer 48:26; Jer 49:12), where in Psa 25:15. it is embodied into a symbolical act. Jahve's cup of intoxication (inasmuch as חמה and חמר, the burning of anger and intoxicating, fiery wine, are put on an equality) is the judgment of wrath which is meted out to sinners and given them to endure to the end.
Verses 9-10
The poet now turns back thankfully and cheerfully from the prophetically presented future to his own actual present. With ואני he contrasts himself as a member of the now still oppressed church with its proud oppressors: he will be a perpetual herald of the ever memorable deed of redemption. לעולם,
