Devarim has a special nature with its idiosyncratic style and unique ideas. Moshe, in his speeches, treats identical topics found in Devarim and in the other books of the Torah with different emphases utilizing specific themes. This provides a convincing response to the questions raised by Biblical scholars from de Witte onwards regarding the disparities between Devarim and other books of the Torah.
The expression "remember that you were a slave in the land of Egypt", which occurs five times over the course of Devarim, is a motif that reflects the emphasis in Moshe's speech on the moral dimension of the commandments, in contrast – or in addition – to the religious aspect that is emphasized in the other books of the Torah. Moshe delivers his speeches as the nation is about to cross the Jordan and enter the land, undergoing a great transformation from a nomadic people to a nation living in its own land. For this reason, Moshe regards it as essential to emphasize the social aspect of the commandments, as a fundamental condition to sustain Israel’s presence in the land for the coming generations.
Moshe's speeches are the only sources in the Torah that treat the relationship between God and Israel from a perspective of love and the reciprocal command for Israel to love God. Only in the Land of Israel can the relationship between God and Israel reach a level that may properly be called "love." For this reason, it is just prior to entry into the land that Moshe permits himself to mention this concept to describe the bond between God and the nation.
The phenomenon of the sanctity of Israel appears so prominently in Devarim. It would seem that on the eve of the entry into the land, Moshe describes a utopian reality – the ideal situation of Israel. The whole nation was indeed supposed to be imbued with the same sanctity as that of the kohanim, but only if Israel were truly deserving of their status as a holy nation. This question – of whether Israel merit God’s benevolence and designation as a holy nation – is one of the central themes of Moshe's speeches throughout Devarim. On the one hand, he asserts that the people are indeed holy. On the other hand, this vision itself hints strongly that this holiness is not automatic; rather, it is contingent upon observance of the commandments. This idea, too, recurs in Moshe's speeches on the eve of the entry into the land.
