Deuteronomy 4:44

וְזֹאת הַתּוֹרָה אֲשֶׁר שָׂם מֹשֶׁה לִפְנֵי בְּנֵי יִשְׂרָאֵל

And this is the law that Moshe set before the children of Israel.

This verse is recited when the Torah is held aloft and displayed to the congregation. In context in the Torah, the words “and this” must refer to some specific referent. The Sforno feels that they refer to what immediately precedes this verse. Rashi feels that the referent is what was to be written after.
