Hear the word of Yahweh, you children of Israel; For Yahweh has a charge against the inhabitants of the land: "Indeed there is no truth, Nor goodness, Nor knowledge of God in the land.
"Nor knowledge of God in the land ..." All of the vain efforts of some expositors to defend the notion that the true God of Israel was actually being worshipped any longer in the Northern Kingdom are defeated in this simple statement.  The knowledge of God had disappeared in Israel, despite the fact of some pagan worshippers using his sacred name alongside that of their pagan idols.  Knowing God in the Biblical sense means an active and obedient knowledge that consciously conforms to the teaching of God's Word.  People who "obey not the gospel of our Lord Jesus Christ" are one in every sense with the people "who know not God"  (2 Thessalonians 1:7-9).
