All Commentaries on Jeremiah 17:9 Go To Jeremiah 17
George Leo Haydock
AD 1849
Perverse. Septuagint, "deep. "
Unsearchable. Septuagint, "man, who shall know him? "(Haydock)
God alone can search the heart by his own power. He enables saints to do it by the light of glory, or of prophecy; as Eliseus and St. Peter knew secret transactions. (Worthington)
