The Torah tells the Midian episode in a sentence. The Targum Pseudo-Jonathan on Exodus (2:21) tells it in a small novel.
"But when Reuel knew that Mosheh had fled from before Pharaoh, he cast him into a pit; but Zipporah, the daughter of his son, maintained him with food, secretly, for the time of ten years; and at the end of ten years brought him out of the pit."
Ten years. In a pit. Fed in secret by a woman.
The Targum's version is astonishing. Reuel — the Midianite priest, the same man the Torah elsewhere calls Jethro — doesn't at first welcome the fugitive. He imprisons him, perhaps to cash in the reward, perhaps out of fear. It is Zipporah, Reuel's granddaughter, who makes a choice. She brings him food. For a decade. She becomes his lifeline.
And at the end of those ten years, Moses comes out of the pit and walks into the bedchamber of Reuel's house — and finds a miracle. "There was shown to him the Rod which was created between the evenings" — one of the ten supernatural things, the sages teach, created at twilight of the sixth day of creation. On it was engraved the Great and Glorious Name. The rod that will divide the Yam Suf and bring water from the rock of Horeb was sitting in Reuel's house, waiting for Moses to emerge and take it.
Then Zipporah is given to Moses as a wife.
The whole narrative is a theology of hidden preparation. For ten years, Moses was in the dark. But the dark was not empty. A woman was feeding him. A rod was waiting. The Memra was keeping schedule.
Beloved, your pit is not your grave. It is your training.
