When Moses sat down with his father-in-law Yithro after the exodus from Egypt, he did not simply give a dry report of events. The Mekhilta explains that Moses "related to his father-in-law" everything — and the word "related" here carries a specific purpose. Moses told the story in a way designed to appeal to Yithro's feelings, to draw him near to the Torah.
This was not manipulation. It was persuasion through wonder. Moses understood that Yithro, a priest of Midian who had worshipped many gods, needed to hear exactly what the God of Israel had done — not as abstract theology, but as lived experience.
So Moses described three categories of miracles. First, "all that the Lord did" — referring to the mighty acts during the exodus from Egypt itself, the plagues and the liberation. Second, "all the ordeals that they had undergone" — the terrors at the Red Sea, when the people stood trapped between the water and Pharaoh's advancing army. Third, the dangers "on the way" — meaning the war with Amalek, who attacked Israel's weakest and most vulnerable stragglers in the desert.
And then the summation: "and the Lord had rescued them" — from everything. Every threat, every enemy, every moment of despair. The cumulative weight of the story did exactly what Moses intended. Yithro heard, and Yithro believed.
