Deuteronomy 10:2

And I will write on the tables the words that were in the first tables, which thou brakest,.... a Though they were hewn by Moses, the writing on them was the Lord's; and the very same laws, in the same words, without any alteration or variation, were written by him on these as on the former; partly to show the authenticity of them, that they were of God and not Moses, of a divine original and not human; and partly to show the invariableness of them, that no change had been made in them, though they had been broken by the people; of which Moses's breaking the tables was a representation;

and thou shall put them in the ark; which being a type of Christ may signify the fulfilment of the law by him, who is the end, the fulfilling end of the law for righteousness to every believer; and that as this was in his heart to fulfil it, so it is in his hand as a rule of faith and conversation to his people.
