Commentary for Exodus 35:30

חור HUR was the son the Miriam (Sotah 11b; cf. Rashi on Exodus 24:14).

He was Miriam’s son. Rashi is answering the question: Why does the Torah trace Betzalel back only as far as Chur? Alternatively, why does it not say, “Betzalel, son of Uri, of the tribe of Yehudah”? Rashi answers that Chur was the son of Miriam, who was a prophetess — and that is why Betzalel merited all this [honor].

ראו קרא, “see! He has called upon, etc.” What does the word: ראו mean here? When Moses had told the people that Betzalel would be the chief architect/craftsman, and that he would be constructing the Tabernacle, (beginning of chapter 31, where he had been told about Betzalel and Oholiov by name by G–d) there was murmuring among the Israelites who charged Moses with nepotism and assigning every position of importance to members of his family. He therefore repeated here that these men had not been chosen by him but by G–d, personally. In fact, Moses, personally, had originally thought that he himself had been charged with the whole task, seeing that G–d had said to him: ועשית , “you will make,” etc., chapter 25,17, and subsequently. The plural impersonal mode had been reserved for the construction of the Holy Ark (Exodus 25,10). G–d explained to him then already that on the contrary, not as he had thought, he would not build the Tabernacle but a descendant of Chur, who had given his life trying to stop the Jewish people from making a golden calf would be charged with that task. By doing so he would help atone for the murder of his grandfather and for the sin of the golden calf. This is why the Torah traces Betzalel’s ancestry to Chur, i.e. Betzalel son of Uri, son of Chur. (Compare Exodus 31,2)
