A Midrash on the 10 plagues reminds us to recognize any good that has been done for us.
Just as the introduction of God's new name represents a shift in our relationship with God, our different names and titles also symbolize different relationships and interactions.
Through Moses and Aaron, God brings plagues on the Egyptians, and Pharaoh repeatedly refuses to allow the Israelites to leave.
Moses and Aaron play complementary roles in communicating God's message of redemption to both the Children of Israel and to Pharaoh.
The unfolding experience of liberation enables the knowledge of new aspects of God.
God tells Moses to remind the Children of Israel that their suffering and redemption is part of an ongoing covenantal process.
The Torah mentions the ages of Moses and Aaron to teach us that age is a source of pride and that by honoring the elderly we bring richness to our own lives.
