פּירוש אויף שמות 6:9

“They would not listen to Moses” [6:9]. Moses came to the Israelites and said to them. I have come to take you out of this exile. The Israelites did not listen to Moses. They had great troubles with the work. They could not catch their breath because of the great amount of work. The Holy One said to Moses. Go to Pharaoh: let him send Israel out of Egypt. Moses responded: How should I go to Pharaoh when the Israelites will not listen to what I say to them? How should Pharaoh listen to my words to allow Israel to go? Even though it was good news for Israel to take them out, yet they did not want to listen to me. How should Pharaoh listen to my words?

God again commanded Moses that he should go to Pharaoh and said: show respect for the king, even if he is an evildoer. Further, it is just to honor a king, even if he is a gentile king. The Holy One commanded Moses that he should not be very angry at Israel.³Rashi, Exodus, 6:13.

ולא שמעו אל משה BUT THEY HEARKENED NOT TO MOSES — they did not accept his words of comfort.
