This book of the law shall not depart out of your mouth, but you shall meditate thereon day and night, that you may observe to do according to all that is written therein: for then you shall make your way prosperous, and then you shall have good success.
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]
