Moses was the prophet that the Lord used in the formation of his covenant people, Israel. Elijah was the prophet that the Lord used in the reformation of his covenant people. Both figures also appear together at the Mount of Transfiguration (Matthew 17:3–4). By referring to these two key figures in Israel’s history, the Lord indicated that he was to bring about a great restoration, a great revival amongst his people.
5 Voici, je vous enverrai Elie, le prophète, Avant que le jour de l'Eternel arrive, Ce jour grand et redoutable.
