Context Summary
Isaiah 5:8–30 contains Isaiah’s dire predictions about the upcoming judgment of Israel. The first “woes” are to the greedy and the pleasure-seeking drinkers. They will go into exile and to the grave for refusing to acknowledge God. The Lord then will be exalted for restoring justice and righteousness. The next woes are to those who embrace sin and mock the coming judgment. These are also those people who have mixed evil and good and believe they know better than God. The final listed woes are those who make it a point of pride how much alcohol they can drink, as well as how they can work the system with bribes. The Lord will summon the armies of the nations to bring judgment on His people.
