21 Therefore hear this, you who are afflicted, who are drunk, but not with wine: 22 Thus says your Lord, the Lord, your God who pleads the cause of his people: "Behold, I have taken from your hand the cup of staggering; the bowl of my wrath you shall drink no more; 23 and I will put it into the hand of your tormentors, who have said to you, 'Bow down, that we may pass over'; and you have made your back like the ground and like the street for them to pass over."
Matthew Henry's Commentary on Isaiah 51:21-23
Commentary on Isaiah 51:17-23
(Read Isaiah 51:17-23)
God calls upon his people to mind the things that belong to their everlasting peace. Jerusalem had provoked God, and was made to taste the bitter fruits. Those who should have been her comforters, were their own tormentors. They have no patience by which to keep possesion of their own souls, nor any confidence in God's promise, by which to keep possession of its comfort. Thou art drunken, not as formerly, with the intoxicating cup of Babylon's idolatries, but with the cup of affliction. Know, then, the cause of God's people may for a time seem as lost, but God will protect it, by convincing the conscience, or confounding the projects, of those that strive against it. The oppressors required souls to be subjected to them, that every man should believe and worship as they would have them. But all they could gain by violence was, that people were brought to outward hypocritical conformity, for consciences cannot be forced.
