Question
Why is Moses' name hardly mentioned in the Haggadah?
Answer
Moses' arguments with Pharaoh, and his bringing all the plagues on the Egyptians, didn't result in the Exodus until G-d Himself stepped in and smote the firstborn. As the Haggadah emphasizes, that plague wasn't brought about by an emissary: "I and not a messenger". The one mention of Moses in the Haggadah, "They believed in Ha-Shem and in Moses his servant", emphasizes that Moses played a secondary role. The emphasis teaches us that we mustn't rely on human leaders even if they are as great as Moses; we must trust that our redemption will come from G-d Himself.
