Jeremiah 12:1

Yet let me talk with thee. — The soul of the prophet is vexed, as had been the soul of Job (Jeremiah 21:7), of Asaph (Psalms 73), and others, by the apparent anomalies of the divine government. He owns as a general truth that God is righteous, “yet,” he adds, I will speak (or argue) my cause (literally, causes) with Thee. He will question the divine Judge till his doubt is removed. And the question is the ever-recurring one, Wherefore doth the way of the wicked prosper? (Comp. Psalms 37:1; Psalms 73:3.) The “treacherous dealing” implies a reference to the conspirators of the previous chapter.

Wherefore are all they happy... — Better, at rest, or secure.
