Exodus 18:2Wrench

So Jethro {Superior}, Moses’ father-in-law, [runs to tell the good news to] Zipporah {Bird}, Moses’ wife, whom Moses had sent back from Egypt [before the Exodus].

Note: Probably at Ex 4:26 Moses sent Zipporah back, when Moses figured out this was not a quickie one-stop Exodus;
that his wife and sons would be murder-targets.
Or Moses and Zipporah were still having the conflicts exposed in the circumcision incident.
The assumption that their relationship was stormy and/or broken is supported by the lack of mention of Zipporah beyond this chapter.
