'Rejected The Law' in the Bible

Thus says the Lord,“For three transgressions of Judah and for four (multiplied delinquencies)I will not reverse its punishment or revoke My word concerning it,Because they have rejected the law of the Lord [the sum of God’s instruction to His people]And have not kept His commandments;But their lies [and their idols], after which their fathers walked,Caused them to go astray.
