But because of your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed.
A day of wrath is that day, a day of distress and anguish, a day of ruin and devastation, a day of darkness and gloom, a day of clouds and thick darkness,
The Lord is a jealous and avenging God; the Lord is avenging and wrathful; the Lord takes vengeance on his adversaries and keeps wrath for his enemies.
