God works with high precision! You've correctly spotted some of the curiosities here--your inquisitiveness is paying off. Fun, isn't it? There's just no end, once you start. God loves us paying close attention, as long as we also get the big picture. I'm finding that seeing all these images really opens my eyes to all sorts of discoveries.
Here's a linguistic one (yours are both physical). When Moses wrote this account (in the second person), why did he refer to Uzziel as "the uncle of Aaron", rather than the more fully correct "Uzziel the uncle of Aaron and Moses"?
I was sad I could only find that single image of them hauling away the corpses. But it speaks to James Tissot's greatness that he saw the importance of it. In a very brief time, for several key reasons, Tissot has become my favorite artist, by far.
There’s more. Why haul by the tunics? The bodies are unclean. The men may remain clean if they only touch the tunics.
I’ve loved Tissot ever since I saw his View From the Cross. Very good use of perspective to tell a story
