Hag 2:17 I struck you and all the products of your toil with blight and with mildew and with hail, yet you did not turn to me, declares the LORD.
Haggai 2:17 represents God’s failed punishments. God had punished Israel for their lack of worship, but His punishment failed to provoke the intended response. This is thematic in the Bible. Punishment is one of many tools God uses to reach Israel within the Bible, but it doesn’t often work.
God is Open 
I have taught for years that one of the themes of the Old Testament is that punishment has no tendency to reform.
That seems to be the case, generally. Kind David might be an exception.
I thing King David repented before he was punished unless you count his conscience bothering, shown by his attempts to cover up the adultery with the murder.
Yes, that seems more accurate.
