Jeremiah 20:12
But, O LORD of hosts, that triest the righteous, and seest the reins and the heart, let me see thy vengeance on them: for unto thee have I opened my cause. But, O LORD of hosts, that triest the righteous, and seest the reins and the heart, let me see thy vengeance on them: for unto thee have I opened my cause.
Jeremiah 20:12 stands within prophecies that denounce sin and express sorrow over the transgression of the people. Those prophecies appeal to the people to return to God. Most of those who hear do not respond to that appeal.
