What do you mean? the rest of what is called the law, the 613?, these are for the most part non applicable many of these rules were for Israel in the wilderness because of the hardness of their hearts and rebellious attitude towards God and for the priests ( ceremonial law) tending the temple/tabernacle. What was put inside the arch of the
covenant were the 2 tablets of stone containing as you know the 10 Commandments, the rest the law, was outside the arch not inside;
Deu 31:24 And it came to pass, when Moses had made an end of writing the words of this law in a book, until they were finished,
Deu 31:25 That Moses commanded the Levites, which bare the ark of the covenant of the LORD, saying,
Deu 31:26 Take this book of the law, and put it in the side of the ark of the covenant of the LORD your God, that it may be there for a witness against thee.
Deu 31:27 For I know thy rebellion, and thy stiff neck: behold, while I am yet alive with you this day, ye have been rebellious against the LORD; and how much more after my death?
Or do you refer to the 2 commandments that summarize the 10 commandments the first part to love God with all our hearts the first four commandments then the rest the last 6 summarizing the last 6 commandments to love your neighbour as yourself?
Mar 12:28 And one of the scribes having come near, having heard them disputing, knowing that he answered them well, questioned him, 'Which is the first command of all?'
Mar 12:29 and Jesus answered him—'The first of all the commands
is , Hear, O Israel, the Lord is our God, the Lord is one;
Mar 12:30 and thou shalt love the Lord thy God out of all thy heart, and out of thy soul, and out of all thine understanding, and out of all thy strength—this
is the first command;
Mar 12:31 and the second
is like
it , this, Thou shalt love thy neighbour as thyself; —greater than these there is no other command.'
Mar 12:32 And the scribe said to him, 'Well, Teacher, in truth thou hast spoken that there is one God, and there is none other but He;
Mar 12:33 and to love Him out of all the heart, and out of all the understanding, and out of all the soul, and out of all the strength, and to love one's neighbour as one's self, is more than all the whole burnt-offerings and the sacrifices.'
Mar 12:34 And Jesus, having seen him that he answered with understanding, said to him, 'Thou art not far from the reign of God;' and no one any more durst question him.
