Question: What is the meaning of the phrase, “since the day I became acquainted with you?”
Answer: It is from the day Moses was called upon to lead his people.
It was still the gift from the Creator! Absolute egoism was breaking out from every point possible in the sons of Israel. So, it was necessary to settle, compare, and constantly make changes in their attitudes toward each other, so they agreed to come out of Egypt.
Moreover, they must be aware of the future state they are going to. This isn’t a physical exit from Egypt to Sinai, but an exit from their egoism, separation from it, rising above it.
This is how the rebelling was expressed. Egoism allowed itself complete freedom of action.
