Only be strong and very courageous, to observe to do according to all the law, which Moses my servant commanded you: don't turn from it to the right hand or to the left, that you may have good success wherever you go.
HOSEA:  Hosea 8:12 has this, "Though I wrote for him my Law in ten thousand precepts!  ...  Many parallels of idiom and language are found between Hosea and the Pentateuch, which show that the latter was extant in the northern Israel, and these can only be accounted for by its existence in a prior written form."[13]
