So it was not you who sent me here: Joseph is addressing all the brothers. So marks a consequence of what has been said in Gen 45.7. See Good News Translation. Revised English Bible says “It is clear that….” In some languages this construction is expressed, for example, as “You [plural] did not send me here; God sent me here” or “God sent me here; you [plural] did not do it.”

Joseph now lists three things God has done with him in Egypt.

He has made me a father to Pharaoh: father in this expression refers to the role of counselor or advisor; as Revised English Bible says, “He has made me Pharaoh’s chief counselor.” In some languages this may be expressed as “king’s advisor” or “the man who advises the king.” In some languages this is “the man who whispers in the chief’s ear.”

LORD of all his house: see 41.40.

Ruler over all the land of Egypt: that is, “ruler of the whole country of Egypt.” See Good News Translation and comments on 41.41 and 41.43. We may also say, for example, “Chief over all the people of Egypt.”
