Another matter: “I am the Lord your God” – Rabbi Abbahu said: This is analogous to a king of flesh and blood who rules but who has a father or a brother.8These relatives of the king are also given great honor. Additionally, if the king dies, he will be succeeded by another member of the royal family. The Holy One blessed be He said: I am not so. “I am first” (Isaiah 44:6), as I have no father; “and I am last” (Isaiah 44:6), as I have no brother; “and besides Me there is no God” (Isaiah 44:6), as I have no son.
Another matter: “I am the Lord your God” – that is what is written: “I related, I saved, and I announced…” (Isaiah 43:12). “I related” to Egypt that you fled, so they would hear, pursue you, and drown in the sea, as it is stated: “It was told to the king of Egypt that the people had fled” (Exodus 14:5). “I saved” you, as it is stated: “The Lord saved Israel on that day” (Exodus 14:30). “And I announced” to the idolaters, as it is stated: “Peoples heard, they were agitated” (Exodus 15:14).
“There was no stranger among you” (Isaiah 43:12) – as it is stated: “Moses sent his father-in-law away” (Exodus 18:27); immediately, “In the third month [from the exodus of the children of Israel from the land of Egypt, on that day they came to the wilderness of Sinai]” (Exodus 19:1). “You are My witnesses, the utterance of the Lord, and I am God” (Isaiah 43:12).
