Moses continues reminding the parents of what their children did not experience Yahweh do for them.

## Neither did they see what he did  ##

Moses is reminding the adults to tell their children all the miracles Yahweh did when they were children.

## what he did ##

"what Yahweh did"

## they pursued after you ##

Here "you" means the Israelites who were alive about 40 years earlier.

## to this place ##

This means the plain of the Jordan River Valley where Moses is speaking to them before they cross over into Canaan.
