Moses went and spoke the following words to all Israel.
Deut. 31:1
The word for “went” here literally means “walked.” Allegorically, then, Moses was telling the Jewish people that the message that he was delivering to them – the Torah in general – is meant to enable them to “walk,” i.e., to constantly progress in their spiritual lives.
On the one hand, walking is a steady, measured form of progress; on the other hand, it distances us totally from our point of origin (as opposed to standing or jumping, for example). Thus, in employing the metaphor of walking, the Torah is teaching us that our relationship with G-d should be characterized by progress so radical that each new step lands us in a totally different place, that our infinite “return” to Him should continually make us into new people, individuals who have left their former selves behind.
This process is ongoing, and will continue until we reach our ultimate goal, the restoration of the world as G-d’s ultimate home, with the advent of the Messianic Redemption.
