Proverbs 29:1 KJV — He, that being often reproved hardeneth his neck, shall suddenly be destroyed, and that without remedy.
The lede of this verse is “time”.
The time period of being “often reproved”.
And then the time period of “suddenly”.
There’s a long period of patiently reproving the person, and then a “sudden” moment of judgement.
Suddenly doesn’t just happen.
