Bezalel was, first of all, of a noble line. His father Hur was a son of Caleb from his union with Miriam, Moses' sister, that Hur who gave his life to restrain Israel from the worship of the Golden Calf. As a reward for his martyrdom, his son Bezalel was to build the Tabernacle, and one of his later descendants, King Solomon, was to build the Temple at Jerusalem. Bezalel was not only of a distinguished family, he was himself a man of distinction, possessed of wisdom, insight, and understanding.
By means of these three God created the world; Bezalel erected the Tabernacle. Through their aid was the Temple complete, and even in the future world will it be wisdom, insight, and understanding, these three that God will employ to set up the new Temple. Bezalel, furthermore, had wisdom in the Torah, insight into the Halakah, and understanding in the Talmud, but more than this, he was well versed in secret lore, knowing as he did the combination of letters by means of which God created heaven and earth.
The name Bezalel, "in the shadow of God," was most appropriate for this man whose wisdom made clear to him what none could know save one who dwelt "in the shadow of God."
