Exo 21:1 called the book of the covenant, Exo 24:4 and which perhaps might be destroyed, as well as the two tables were broken; and therefore upon the renewal of the covenant here, there is a repetition made of the principal laws before given, which are ordered also to be written in a book, which may very well be called by the same name, since it follows: for after the tenor of these words I have made a covenant with thee and with Israel, with Moses, as their representative and mediator, and with them represented by him: what is above related carries in it the form of a covenant between them, God having declared on his part what he would do for them, and what laws and rules he required to be observed on their part; which Moses assented to in their name, and was ordered to write them down, that he might repeat them to them.
