innweekly parsha when yosef let his brothers go he said dont be angry? what does it mean in deeper meaning why he said this?

Shalom, Thank you for your question. You are referring to the verse in Berashit 45,24 where Yosef tells his brothers not become angry on their return trip to Israel. Rashi explains this in three different ways – 1. Do not become involved in a deep Torah argument less you loose your way. 2. Do not become “angry” in the sense of travelling to quickly in order to reach home faster and thus endanger yourselves. 3. (And this is the simple plain meaning of the text) do not argue as to who was at fault for selling Yosef and who needs to take blame. I hope this is of some help. Blessings.
