It is a small verse, easy to read past, but Targum Pseudo-Jonathan on Exodus 35:1 marks a turning point. Moses gathers all the congregation of the sons of Israel, and says to them: These are the things which the Lord hath commanded to be done.
The Targum notes the scope: all the congregation. Not the elders alone, not the heads of tribes, not Aaron and his sons. Everyone. The rabbis of Midrash Tanchuma (Vayakhel 1) explicitly connected this verse to the idea that Torah was always meant to be taught to the whole people, not hoarded by a priestly caste. Moses did not brief the committee; he summoned the nation.
And what is the first thing he teaches? The Sabbath (Exodus 35:2, in the next verse). Not the Tabernacle construction, though that is where the parsha is heading. Sabbath first. The rabbis read a lesson into the order: even the sacred work of building God's house is suspended on the seventh day. The Mishkan could wait. The rhythm of rest could not.
There is also a thread here about what happens after sin. The previous chapters described Israel's catastrophic fall into the golden calf. Now, in the Targum's telling, Moses gathers them again. The nation that shattered the first tablets is the same nation summoned here. The covenant is renewed not by excluding the failed, but by reconvening them.
The takeaway: Judaism is never a religion of the remnant. Every time the people are rebuilt, they are rebuilt whole — all the congregation, every voice, gathered again to hear what God has asked.
