Psalms 75:8

For in the hand of the Lord there is a cup, that of God's wrath, Cf Isaiah 51:17, and the wine is red, foaming and frothing with its strength; it is full of mixture, God Himself having prepared the fermenting liquid; and He poureth out of the same, serving it with His own hand while it is foaming; but the dregs thereof, all the wicked of the earth shall wring them out and drink them, the guilty being constrained to drink the entire cup of God's wrath without intermission, the mention of the dregs signifying the thoroughness with which God would carry out His punishment. This statement having been made, the psalmist again takes up the strain of his praise.
