Exodus 34:27

Write thou these words. — Heb., Write for thee these words, i.e., put them in writing for thine own use and the use of thy people. This express command accounts for the assignment of so much space to what is mainly repetition. The requirement of the repetition can only be explained by the importance of the laws laid down under the circumstances of the Hebrew nation, and the power of repetition to enforce upon the conscience what is pressed upon it by reiteration.

After the tenor of these words. — The summary of positive laws contained in this chapter (Exodus 34:12) was not intended to supersede the “Book of the Covenant,” but rather to confirm and reinforce it. The covenant was renewed not upon these words only, but “after the tenor,” i.e., after their general aspect or bearing.
