ישעיהו נא:יז פירוש: רש״י, מלבי״ם ואבן עזרא

dregs Heb. קֻבַּעַת. Jonathan renders: פַּיְלֵי, which is the name of a cup [phiala in Latin]. But it appears to me that קֻבַּעַת, these are the dregs fixed (קְבוּעִים) to the bottom of the vessel, and the word מָצִית, “you have drained,” indicates it, as it is said (Ps. 75:9): “...shall drain (יִמְצוּ) its dregs.”

"Awake, awake" You. In response to what you said to Me, 'Awaken, awaken, dress yourself with strength, O arm of the Lord' (Is.51:9) I say

Which hast drunk, etc. Israel is compared to a man that is drunk, and is not aware of what is done unto him; he lies down in deep sleep.
