NIV

KJV

KJV
They rejected his decrees and the covenant he had made with their ancestors and the statutes he had warned them to keep. They followed worthless idols and themselves became worthless. They imitated the nations around them although the LORD had ordered them, "Do not do as they do."
NIV
They despised and rejected His statutes and His covenant which He made with their fathers and His warnings to them, and they followed vanity (false gods--falsehood, emptiness, and futility) and [they themselves and their prayers] became false (empty and futile). They went after the heathen round about them, of whom the Lord had charged them that they should not do as they did.
AMP
And they rejected his statutes, and his covenant that he made with their fathers, and his testimonies which he testified against them; and they followed vanity, and became vain, and went after the heathen that were round about them, concerning whom the LORD had charged them, that they should not do like them.
