Contradiction with Joshua 1:7
While Joshua 23:6 emphasizes adhering strictly to the law given by Moses, Joshua 1:7 also commands strength and courage in adherence but without specifying the complete exclusion of other considerations, focusing instead on prosperity and success.
Joshua 1:7: Only be thou strong and very courageous, that thou mayest observe to do according to all the law, which Moses my servant commanded thee: turn not from it [to] the right hand or [to] the left, that thou mayest prosper whithersoever thou goest. [prosper: or, do wisely]
Contradiction with Romans 6:14
This verse contradicts the Old Testament emphasis on following the law by stating that believers are not under the law, but under grace, which suggests a shift from strict adherence to the Mosaic Law.
Romans 6:14: For sin shall not have dominion over you: for ye are not under the law, but under grace.
Contradiction with Galatians 3:10
It highlights that reliance on the works of the law can result in a curse, contrasting with the directive in Joshua 23:6 to be very courageous in keeping the law of Moses.
Galatians 3:10: For as many as are of the works of the law are under the curse: for it is written, Cursed [is] every one that continueth not in all things which are written in the book of the law to do them.
Contradiction with Romans 3:28
This verse states that a person is justified by faith apart from the deeds of the law, which contrasts with Joshua 23:6's focus on law adherence as central to righteousness.
Romans 3:28: Therefore we conclude that a man is justified by faith without the deeds of the law.
